| Filters and Dampers
E type models are supplied complete with a fan cabinet that is designed to incorporate integral filters and dampers. The fan cabinet has full size easy access panels. As an option the cabinet may be fully insulated.
Filters are arranged in a vee bank formation. This ensures that both fresh air and re-circulated air are filtered on mixed air applications and the quality of the environment being heated is maintained.
Standard filter options offer either 25mm disposable panels or 50mm pleated EU4 synthetic panels.
Dampers may be fitted to the top, bottom, or rear of the cabinet. They may be adjusted either manually or by a servo-motor fitted inside the cabinet. Two position, three position or modulating damper motors may be specified.
Where units operating on 100% fresh air require an inlet damper these should be specified complete with an end switch.
Units supplying fresh and/or return air may be operated via an integral linkage and single damper motor for top and rear or bottom and rear damper combinations.
For installations requiring a top and bottom damper combination two servo-motors are required.
All access panels to filters and damper actuators are located on the same side as the access to the heater section.
