The Red Dot 73R9204 In-Line Booster Pressurizer is engineered to increase airflow in cab ventilation systems that utilize remote-mounted air filters. Operating on 24V DC, this unit helps overcome airflow restrictions caused by extended hose runs or filter placement, delivering improved air circulation to the cab.
This pressurizer is designed exclusively for use with Red Dot remote mount filters 78R5100 and 78R5110. Installed inline, it supports more effective ventilation and defrosting in heavy-duty trucks and off-highway equipment.
Important Fitment Note:
This booster is intended only for use with the specified remote filter assemblies. 3-inch defrost hose (78R0300) is sold separately.
