Accessories

Cover plates from exodraft allows you to cover the soundproofing rockwool mat under the chimney fan for a more aesthetically pleasing look while protecting it from weather influences and animals.

The cover plate also comes with an insert sleeve for mounting a temperature sensor, if you have an exodraft control unit with temperature monitoring.

• Allows you to cover the soundproofing rockwool mat under the chimney fan
• FRxAFD versions are intended for use on steel chimneys with one of our corresponding FR flanges.
• FRxAFD-001 versions are intended for use on brick / masonry chimneys and can be placed directly on the chimney with a layer of mineral wool between.

EBC22/24 control relay box.

When more than a couple of boilers are attached to a chimney, a relay box can be applied to as much as four boilers.

If you require more than a quartet of boilers, you can connect an extra pair of relay boxes. A total of eight boilers can be controlled for each EBC20/22.

The EFC21 controls are used in association with the gas solenoid valves of the exodraft, which allows the gas to be opened and closed based on the EFC21 control’s input.

Once the gas supply is opened by the valve and the proper flow in the chimney is determined, the combustion can start.

If the control senses a minimal flow amount, the valve will close. This will eliminate the risk of gas emission.

The frequency inverters – or variable speed drives (VSD) – are used for regulating the speed of the chimney fans with three-phase motors.

All CFIR inline fans have special EC (electronically controlled) motors that can only be regulated by using a frequency inverter. The inverters are used in combination with the controllers EBC22/24 or the manual controller Pot S.

All FRK frequency inverters are pre-programmed with a unique software tested and designed to suit each fan.

When pairing our chimney fan with original exodraft accessories, you take comfort in knowing that everything will operate as they should, and will for another 2 to 3 decades.

We provide the following chimney fan mounting accessories:

• Protection from driving rain
• Covers for steel chimneys and masonry chimneys
• Vibration damper that tones down the vibration flow from the chimney fan to the chimney/building
• Mandatory maintenance switch (for turning off the current for maintenance/cleaning purposes)
• Screws for stable and safe chimney fan mounting

An exodraft flange is placed underneath the chimney fan, producing a safe and stable transition between fan and chimney.

• Vibration dampers
• Manufactured from stainless steel (1.4301 (304))
• Option to order different sizes
