Hammond PF6600AT3RBK460 462 CFM Reverse Flow Type 3R Fan, 460V AC, Black

PF6600AT3RBK460 is an outdoor-rated Type 3R filter fan in Black, the reverse-flow 462 CFM model in the 12.6 in housing size. It is a 460V AC unit from the Reverse Flow Design table of the 3RFF Outdoor FilterFans series, rated 462 CFM free flow, for panel builders and integrators ventilating enclosures that sit outdoors in rain, ice and direct sun. This is the 460V AC version; the technical data groups it with the 400/460V supply rating, for panels fed from higher-voltage supplies.

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 12.6 in x 12.6 in x 6.2 in (320 mm x 320 mm x 157 mm); the ordering table lists H 12.60 in (320 mm), W 12.60 in (320 mm) and D 6.18 in (157 mm). Shipping weight is 3.5 lbs (1.59 kg). Installation uses the patented Click & Fit design for hardware-free mounting. Pair it with the matching outdoor-rated exhaust filter PFA60000T3RBK, which uses an 11.46 x 11.46 in (291 x 291 mm) cutout. The same fan is offered in the other color as PF6600AT3RLG460.

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. PF6600AT3RBK460 is REACH and RoHS compliant, with UPC 623980430621 and UNSPSC 39121302.
