eFans UK: A Practical Guide to Ventilation Fans, Ducting and Components

Choosing ventilation equipment can feel like assembling a puzzle: the fan, duct, grille and controls all need to fit the job. eFans is a UK-focused supplier of ventilation products, with a catalogue that ranges from small duct fittings to large commercial fans. Whether you are planning a bathroom extract run or comparing equipment for a commercial building, understanding the product types can help you narrow your options.

This guide explores the kinds of products represented in eFans’ catalogue, explains what to consider when comparing them, and highlights selected items and their listed prices from the reference data. Those prices are examples, not a promise that a product is in stock or that the price will remain unchanged. Shipping details were not provided, so check the retailer’s own information before placing an order.

What can you find at eFans?

The products in the supplied catalogue focus on ventilation and air movement. They include centrifugal box fans, roof-mounted extract fans, heat recovery equipment, speed controllers, ducting, grilles, airbricks and fire-protection components. That breadth makes the range relevant to more than one kind of project, from a small duct connection to a larger supply or extract system.

There are products from established ventilation manufacturers, including Elta, Domus Ventilation, Systemair and Vent-Axia. The selection also includes items listed under the eFans brand, such as flexible ducting and pressed steel grilles. Rather than treating all these products as interchangeable, start with the system you need to build or maintain. A powerful fan will not solve a problem if its connections do not match the ductwork, for example.

Small components and larger equipment

At one end of the range are parts such as a Domus 100mm-to-80mm duct adaptor, listed at £4.74, and a Domus 927 straight connector with damper for 220 x 90mm Megaduct, listed at £8.04. At the other end are large fans designed for high-volume ventilation. An Elta Qube SQU82 560-EC-1 box fan is listed at £3,837.02, while a Systemair DHS Sileo 355 roof fan is listed at £905.99.

These examples show why it helps to compare products by function, not just by price. A connector and a fan do different jobs, so a lower price does not mean better value if the item does not suit your installation.

Fans for domestic and commercial ventilation

Fans are among the most technical products in the eFans selection. The data includes centrifugal box fans for supply or extract systems, roof-mounted extract fans, and a whole-house mechanical ventilation with heat recovery unit. Each type suits different system layouts and operating needs.

Box fans and system requirements

Elta’s SSDL and Qube product examples illustrate two types of centrifugal box fan. The SSDL range includes models with different duct connection styles, such as circular or rectangular spigots. Some versions have a pre-fitted terminal box, while others do not. These details can affect how easily a fan connects to the rest of the system, so check the exact model description rather than relying on the product family name alone.

For instance, the Elta SSDL315-1EC-T has 315mm circular spigots and a terminal box. Its listed price is £1,405.99. The SSDL315-1EC-R has rectangular spigots and no terminal box, and is listed at £1,376.99. Both descriptions give a maximum free-air figure of 2,376 cubic metres per hour, but the connection and electrical details differ.

The Elta Qube range includes larger box fans intended for supply or extract in ducted systems. The SQU67 450-EC-1 is listed at £2,268.60 and has a stated maximum free-air airflow of 7,132 cubic metres per hour. The larger SQU82 560-EC-1 is listed at £3,837.02, with a stated maximum free-air airflow of 9,302 cubic metres per hour. These figures are product specifications, not a guarantee of the airflow a completed installation will deliver. Duct resistance and system design matter too.

Roof-mounted extract fans

Systemair DHS Sileo products in the catalogue are roof-mounted extract fans. The supplied examples include single-phase and three-phase models, with different diameters, airflow figures and operating characteristics. For example, the 400E4 model is listed at £996.99 and has a stated maximum airflow of 4,273 cubic metres per hour. The 450 three-phase version is listed at £1,099.99, with a stated maximum of 5,998 cubic metres per hour.

When comparing roof fans, pay attention to electrical supply, discharge direction, speed control, maximum air temperature and the required protection arrangements. A fan that looks suitable by diameter may still be wrong for a particular building or duct route. If you are unsure, ask a qualified ventilation professional to check the specification and installation requirements.

Heat recovery and ventilation controls

For whole-house ventilation, the catalogue includes the Vent-Axia Integra Heat Recovery Unit 456864. The supplied description identifies it as a mechanical ventilation with heat recovery unit for smaller residential or commercial applications up to 180 square metres. It is listed at £892.99 and has a stated heat recovery efficiency of up to 70%, with airflow up to 49 litres per second.

The unit uses separate incoming and outgoing air streams that pass through a heat exchanger. According to the product description, the streams do not mix; heat transfers between them. The listing also mentions condensation control and a summer mode. These features may be relevant when planning a system, but the right equipment depends on the building and the ventilation design.

Controls are another part of the picture. The Vent-Axia SC5001 electronic speed controller is listed at £105.99. Its description specifies single-phase operation and stepless speed control for compatible AC fans, as well as remote on/off contacts and an alarm output. Compatibility is important: do not assume a controller will work with every fan. Check the fan’s electrical details and the manufacturer’s guidance.

Ducting, grilles and air terminals

Ducting carries air through the system, while grilles and terminals provide the connection between the duct and a room or the outside. These supporting parts may seem less exciting than a fan, but they can have a big effect on whether the installation fits together neatly.

Flexible and insulated ducting

The catalogue includes eFans-branded combi flexible ducting in 127mm and 152mm diameters, both supplied in 6m lengths. The 127mm version is listed at £12.95 and the 152mm version at £18.63. Their descriptions specify an aluminium inner layer and a PVC outer layer, and state that they are suited to low- and medium-pressure ventilation.

For runs through unheated areas, insulated ducting may be worth considering. The Domus 6210 Easipipe product is a 150mm-diameter, 10m insulated aluminium duct listed at £106.69. Its description says the insulation can reduce condensation, heat loss and noise. A separate Systemair insulated flexible duct listing is 406mm in diameter and 10m long, priced at £195.99.

Grilles and external terminals

For external walls, the Domus plastic louvred wall grille is available in several colour options in the supplied listings, including white, grey, brown, Cotswold and terracotta. The 125mm versions shown are listed at prices from £9.50 to £10.13, depending on the listed colour. The description specifies a fitted flyscreen and a louvred face designed to help keep out driving rain and insects while allowing air through.

Other options include Domus louvred airbricks for rectangular ductwork and pressed steel grilles for wall or door mounting. The 300mm x 300mm silver pressed steel grille is listed at £108.99, while the 400mm x 400mm white version is listed at £119.99. These grilles are described as having a 67% free area and as suitable for internal or external use. Check the opening dimensions and the product’s overall size before choosing a replacement.

Fire protection components

Some ventilation installations need components that help limit the spread of fire through ductwork or wall penetrations. The catalogue includes Systemair circular in-duct fire dampers for spiral ductwork, with a stated maximum fire resistance of 120 minutes. The supplied listings include several diameters: the 100mm model is listed at £58.06, the 125mm model at £64.99, the 150mm model at £79.77 and the 200mm model at £105.99.

The data also includes a Domus DFS110 fire sleeve for 110 x 54mm System 100 rigid duct, listed at £26.81. Its description states that it is intended for use where duct passes through a fire-compartment wall and offers up to 120 minutes of fire resistance. Fire protection depends on the component, the surrounding construction and correct installation. Always check the relevant technical information and project requirements rather than choosing a part based on its headline rating alone.

How to compare eFans products

Before buying, write down the key requirements for your project. That simple step can turn a crowded catalogue into a manageable shortlist. For a fan, record the required airflow, duct size, available electrical supply, operating conditions and installation location. For ducting or a grille, check the shape, diameter, length, material and connection type.

Match connections and dimensions

Dimensions are not minor details. A round duct and a rectangular duct need different connections, and a grille’s nominal face size may not be the same as its overall size. The catalogue’s pressed steel grilles, for example, are described as approximately 45mm larger overall than their nominal face measurement. Measure the opening and compare it with the product drawing or specification.

Read performance figures in context

Maximum airflow figures can help you compare models, but they do not tell the whole story. Some fan listings also give airflow at stated pressure levels. That is useful because a real duct system creates resistance, and performance can change as pressure rises. Treat the figures as a starting point for selection, not as a substitute for system design.

Also check operating limits. Several Elta Qube descriptions specify a maximum airstream temperature of 50°C and state that the models are not suitable for corrosive or explosive atmospheres. A different fan in the catalogue, the Elta Clearflow CFHT500 roof fan, is described for air temperatures up to 120°C. Those distinctions matter: products that look similar may be intended for very different conditions.

Prices, availability and delivery information

The prices in this guide are the amounts shown in the supplied reference data. They should be treated as examples, not as a current quote. The reference data does not provide shipping costs, delivery times, stock status, returns terms or discount details. Check eFans’ own website for the latest product, price and delivery information before ordering.

If you are comparing options through ZoneOffer, remember that ZoneOffer is a comparison site, not the retailer. Use comparison information to explore alternatives, then verify the final details with the seller. This is especially useful for technical items, where the exact model, connection type and specification can matter as much as the headline price.

Is eFans right for your project?

eFans’ listed range covers a wide span of ventilation needs, from adaptors and external grilles to large commercial fans and heat recovery equipment. That can be useful when you are sourcing several parts for one system or comparing models from different manufacturers. The most important step is to define the job clearly, then match each product to the required airflow, dimensions, electrical supply and operating conditions.

For straightforward replacement parts, careful measuring may be enough to guide your shortlist. For a complete ventilation system, a high-capacity fan, or any fire-safety component, technical advice and correct installation are essential. Use the catalogue as a way to identify possible options, and confirm the specifications before you commit.
