Hammond PF22000T3RLG24 38 CFM Outdoor Type 3R Filter Fan, 24V DC, Light Gray

PF22000T3RLG24 is an outdoor-rated Type 3R filter fan in Light Gray, the compact 38 CFM standard-flow model, the smallest housing in the 3RFF Series. It is a 24V DC unit from the Standard Flow (Pressurize) Design table, rated 38 CFM unimpeded and 28 CFM when installed with one filter fan and one exhaust filter. This is the 24V DC version, one of the DC voltage options the series configurations list alongside 115VAC, 230VAC and 460VAC.

The series is designed for outdoor weather where resistance against falling rain, ice formation and UV degradation is important, and it maintains a UL tested NEMA Type 3R seal against the enclosure without the need for a rainhood. The housing plastic is heat resistant UL 94 V0 fire approved ABS, and the fluted filter mat holds more dust before it impedes airflow, extending the mean time between maintenance - a point that matters for remote sites.

The part page gives the size as 5.7 in x 5.7 in x 2.8 in (145 mm x 145 mm x 71 mm); the ordering table lists H 5.71 in (145 mm), W 5.71 in (145 mm) and D 2.76 in (70 mm), with a cutout of 4.92 x 4.92 in (125 x 125 mm). Shipping weight is 1.8 lbs (0.82 kg). The patented Click & Fit design gives hardware-free installation, and the matching exhaust filter is PFA20000T3RLG. The same fan is offered in the other color as PF22000T3RBK24.

The installation manual lists Type 3R/IP55 protection, which depends on correct installation position and an undamaged foam gasket, and calls for a minimum of 12 in (30.5 cm) between arcing parts and filters per UL508A sec. 22. PF22000T3RLG24 is REACH and RoHS compliant, with UPC 623980430065 and UNSPSC 39121302.
