eFans UK: A Practical Guide to Its Ventilation Products and Range

What is eFans?

Looking for ventilation equipment can feel a little like assembling a puzzle: a fan is only one piece, and ducting, connectors, filters and controls may all matter too. eFans is a UK-focused online retailer whose listed range covers many of those parts, from small duct fittings to larger ventilation units and roof equipment.

The products in the supplied catalogue include items from Domus Ventilation, Systemair and Vent-Axia, as well as products listed under the eFans brand. The selection points to a store aimed at people planning or maintaining ventilation systems, including household projects and more demanding commercial or industrial installations. The catalogue includes both individual components and complete equipment, so shoppers can browse around a particular installation need rather than looking only for a standalone fan.

That is useful if you already know the system type or component you need. If you are new to ventilation, though, the range’s technical names and measurements may take some sorting. A connector that looks close to the right size is not necessarily the right fit. Checking the product description and matching every connection to your system is a sensible first step.

What can you buy from eFans?

The catalogue covers several broad areas: ducting and fittings, fans, whole-house ventilation equipment, filters, controls and roof-related accessories. That variety gives shoppers a chance to look for connected parts in one place. It does not, by itself, confirm that every possible size or accessory is available, so check the specific listing for the item you need.

Ducting, connectors and ventilation fittings

Many of the listed products are fittings for rigid duct systems. Domus examples include straight connectors, bends, adaptors, end caps, duct clips and wall plates. These parts help connect, secure, redirect or finish a duct run. The catalogue includes parts for Domus systems such as Supertube, Easipipe and Megaduct, with product descriptions giving sizes and connection types.

For example, the Domus 510 Supertube product is a one-metre length of 204 x 60mm rigid flat duct, while the Domus 520 is a straight connector for two lengths of the same duct profile. There are also adaptors that bridge different duct diameters or profiles, such as a 100mm-to-80mm round adaptor and a Megaduct-to-Supertube adaptor. These examples show why it helps to check the measurements closely before ordering.

Some fittings do more than join duct. The Domus 594, for instance, is a 125mm Easipipe straight connector with a built-in backdraught damper. Its described purpose is to help stop outside air travelling back down the duct when the fan is off. Other listings include louvred outlets and external wall grilles, including a 125mm round grille with a flyscreen.

Fans and ventilation units

For shoppers looking for a fan rather than a fitting, eFans lists several types. These include inline duct fans, roof fans, window and wall fans, and whole-house ventilation units. The right category depends on the installation and the job the fan needs to do; the product descriptions provide technical details that can help narrow the options.

Vent-Axia examples include ACM mixed-flow inline fans for 100mm and 150mm duct, and an SLP100EC Slimpak inline box fan for 100mm duct. The catalogue describes the ACM100 as delivering up to 288 cubic metres per hour in free air, and the ACM150 as delivering up to 576 cubic metres per hour in free air. Those are stated product figures, not a guarantee of performance in every installed system.

There are also larger products for other settings. Systemair listings include DHS Sileo roof fans, with the 450mm three-phase model described as delivering up to 5,998 cubic metres per hour and the 500mm single-phase model up to 7,283 cubic metres per hour. The catalogue also includes Vent-Axia Sentinel whole-house ventilation products, such as an MVHR unit and an MEV unit. Their descriptions give details such as airflow, controls and installation context.

Filters, controls and roof accessories

Other parts of the range support the wider ventilation system. Systemair FGR filter cassette boxes are listed in several duct diameters, including 200mm, 250mm, 315mm and 355mm. The descriptions say these boxes come with a G3 panel filter and are intended for supply-air filtration in heavy industry and industrial workshops. Separate filter listings include a Systemair bag filter suitable for specified filter cassettes.

Controls appear too. One example is a Vent-Axia remote speed control for EC fans, offering 0–10V DC speed adjustment and an on/off switch, according to its product description. Roof-related accessories include backdraught shutters, purlin boxes and soaker sheets. Some of these items are listed as made to order; the reference information gives an estimated lead time of two to three weeks for particular soaker sheets and purlin boxes.

How to choose the right product

Start with the system you have, not just the product name. Note the duct shape and size, the fan or unit connection, and whether the part needs to fit a particular Domus system or another product family. A 204 x 60mm flat duct fitting and a 125mm round duct fitting are not interchangeable simply because both are used for ventilation.

Next, think about the role of the component. Do you need to join two lengths, reduce or increase a duct size, make a bend, terminate a run, or control airflow? Product names often signal the basic job: “straight connector”, “elbow”, “adaptor” and “end cap” each describe a different function. Read the full listing to confirm details such as connection type, material and any included feature, such as a damper or filter.

For fans and ventilation units, compare the specifications that match your project. These may include duct diameter, airflow, motor type, voltage, speed control, installation position and stated application. A high airflow figure alone does not tell you whether a fan is right for your system. If electrical work or system design is involved, use a qualified professional where appropriate; some product descriptions specifically call for installation by a qualified electrician or competent person.

It can also help to build a parts list before buying. Sketch the duct route and mark each transition, bend, joint and external termination. Then check the product dimensions against that plan. This simple step can help avoid ordering a component that appears similar but has the wrong profile or connection size.

Prices and value

The reference catalogue shows a wide spread of listed prices, reflecting the difference between a small fitting and a substantial fan or ventilation unit. For example, the Domus 522 Supertube duct clip is listed at £0.91, while the Domus 510 one-metre rigid duct is listed at £9.73. Larger equipment is priced much higher: the Systemair DHS Sileo 450 roof fan is listed at £1,099.99, and the Vent-Axia Sentinel Kinetic B MVHR unit at £1,159.99.

These are catalogue prices supplied in the reference data, not a promise that a price will remain unchanged. The data does not provide a general discount, promotion or delivery charge, so it would be unwise to assume that an item is on sale or that shipping is free. Check the current listing and checkout details before making a purchase.

To judge value, consider the whole requirement rather than comparing one item in isolation. A low-cost connector is only useful if it fits the rest of the system. For larger equipment, compare the relevant specifications and installation needs, not just the price. The right choice is the one that matches the system and purpose, rather than simply the cheapest or most powerful option.

How eFans compares with other UK retailers

In the UK market, ventilation equipment can be found through specialist suppliers, general building merchants and online retailers. At a broad level, a specialist catalogue such as eFans may be useful when you want to browse technical ventilation components alongside fans and related accessories. General merchants can serve wider building needs, while other specialist sellers may focus on different product ranges or support services.

The supplied data does not give reliable evidence for a detailed comparison of eFans with named competitors. It does not establish differences in customer service, delivery speed, stock levels, returns, warranties across the whole range or overall price competitiveness. Treat those as points to check directly rather than assuming eFans is better or worse than another UK seller.

A practical comparison is to search for the exact model or compatible component across retailers, then check the full specification and the final checkout cost. Confirm that the product matches your duct system and installation before comparing prices. For specialist equipment, a small difference in model number or connection size can matter more than a small difference in the headline price.

What to check before ordering

First, confirm the dimensions and system compatibility. The product data often identifies duct sizes, materials and the system a fitting belongs to. Match these details to your existing equipment or installation plan. If a product description is unclear, seek confirmation before placing an order rather than relying on a similar-looking item.

Second, check the current product page for availability and delivery information. The reference data does not provide general eFans shipping details or a store-wide delivery policy. It does identify certain made-to-order items with estimated lead times of two to three weeks, but that detail applies to those listed products and should not be treated as a general shipping promise.

Finally, review the warranty and installation notes attached to the individual product. The catalogue gives manufacturer warranty details for some items, including one-year warranties on many listed Domus fittings and a two-year warranty for certain Vent-Axia products. Coverage is product-specific, so check the particular listing rather than assuming one warranty applies across the store.

Is eFans a good fit for your project?

eFans may suit shoppers who already have a clear idea of the ventilation part or system they need. Its listed selection spans small duct fittings, fans, filters, controls and larger ventilation equipment, with product descriptions that include useful technical details. That makes it possible to explore more than one part of a ventilation setup in the same catalogue.

If you are still working out what your project requires, take time to identify the duct sizes, system type and performance needs first. Ventilation products are not always plug-and-play choices: the right fit depends on how the complete system is designed. When you are unsure, professional advice can help you avoid mismatched parts or unsuitable equipment.

Overall, eFans is best approached as a technical product catalogue rather than a place to choose by name alone. Read the specifications, check the current price and delivery information, and confirm compatibility before ordering. With those checks in place, you can shop more confidently and focus on the part that actually fits your ventilation plan.
