Filters and Air Cleaners


Cleanflow Air Cleaner

When your air heater is operating on maximum load, all of the air within the dwelling passes across the air filter 6 times per hour. This presents the perfect opportunity to electronically clean the air and remove smaller particles such as pollen, mould and cigarette smoke.


The Cleanflow principle is simple and highly effective. It works by polarising the filter media and thereby the particles are attracted to it. Any particles that are not caught by themedia have no polarised charge, so will not adhere to soft furnishings or walls and will be caught on subsequent passes.

The electronic screen is charged and in turn polarises the filter media. Particles are then attracted to, and captured within the media pads. Cleanflow will remove 95% of particles down to 1 Micron.

The illustration below shows various particles magnified 1000 times.

Grilles and Registers



These are usually sited in the wall at low level (low side wall) or at a high level (high side wall) They have a lever to adjust the rear vanes to direct airflow in a downward projection.






These are usually sited in heater compartment doors for compartment cooling and to provide air for combustion. Also used for relief air from heated rooms.




Ceiling Deffuser

Ceiling Diffuser

These are sited in the ceiling.




Floor Diffuser

Floor Diffuser

These are sited in the floor.



The amount of heat introduced into the room is dependent upon the 'Free Area' of the register or diffuser. When they have been in use for a number of years, the free area is reduced by decorating. This reduction can be as much as 50%. Therefore, improvements can be made to an existing system by simply replacing the registers or diffusers.
