Accessories | JMS.Guidance for specification option: Sealing frame – For mounting a roof fan on an up stand or base. – Supplied with screws and gasket for a complete weatherproof seal JBS.Guidance for specification option: Flat roof up stand For mounting a fan on a flat roof without up stands. – For use on horizontal roofs. – Internal insulation to prevent condensation. – Supplied with screws and gasket for a complete weather seal. JPA.Guidance for specification option: Accessory adapter plate – Used when mounting the accessories (JCA, JBR, JAE). – Allows the fan to be disconnected from the upstand without having to remove the duct. JCA.Guidance for specification option: Backdraft shutter – Prevents backdraft when the fan is not operating. – To be mounted at the fan inlet with the JPA plate. JCA N.Guidance for specification option: Backdraft shutter – Prevents backdraft when the fan is not operating. – To be mounted at the fan inlet with the JPA plate. JBR N.Guidance for specification option: Flange – For use when circular connection is required directly to the fan. – To be mounted at the fan inlet with the JPA plate or fixed directly to the fan base (rivets or screws not supplied). JAE N.Guidance for specification option: Flexible coupling – Reduces the transmission of vibrations when the duct is connected directly to the fan. – To be mounted at the fan inlet with JPA plate. JCC.Guidance for specification option: Adapter for circular duct – For use when fitting the models up to 400, directly to a spirally wound circular duct. BI.Guidance for specification option: Support base for inclined curb mounted installations – To ensure a proper installation of the MAXTEMP roof fan it is essential to specify the roof pitch angle and the distance between the roof beam profiles. JAA.Guidance for specification option: Support base for inclined curb mounted installations – To ensure a proper installation of the MAXTEMP roof fan it is essential to specify the roof pitch angle and the distance between the roof beam profiles. AIRSENS-CO2.Guidance for specification option: IAQ intelligent sensors that incorporates an internal CO2 or VOC or HR sensor. AIRSENS-RH.Guidance for specification option: IAQ intelligent sensors that incorporates an internal CO2 or VOC or HR sensor. AIRSENS-VOC.Guidance for specification option: IAQ intelligent sensors that incorporates an internal CO2 or VOC or HR sensor. CONTROL ECOWATT BASIC.Guidance for specification option: Speed control and single-phase ON/OFF. CPFL-S / CPFL-E.Guidance for specification option: Presence detector. REB-ECOWATT.Guidance for specification option: Speed controller for fans fitted with EC motor TDP-D.Guidance for specification option: Presure sensor without display TDP-PI.Guidance for specification option: Presure sensor with display.
