Hammond DTFK1AC150E 105 CFM Thermostat Exhaust Fan Kit, 120V

The DTFK1AC150E is a thermostat-controlled exhaust fan kit for rack cabinets and industrial enclosures, intended for IT and AV integrators, control panel builders, and facilities teams that need supplemental airflow only when heat actually builds up. It is rated 115 VAC, moves 105 CFM unimpeded, and uses the standard 4.70 in (119 mm) fan size, making it suitable for many Hammond products featuring the standard 4.7-inch fan opening.

An integrated adjustable thermostat switches the fan on as enclosure temperatures rise and off again once the set point is restored, with an adjustment range of 32°F to 140°F (0°C to 60°C). Compared with continuously running cooling, this reduces noise, energy consumption, and fan wear. Noise is rated at 56 dB, measured at 12 in to 24 in from the source. The kit operates from -20°C to +60°C at 5% to 95% non-condensing humidity.

DTFK1AC150E is supplied as a complete kit: the fan with integrated thermostat, a 6-foot (72.00 in / 1829 mm) power cord terminated in a NEMA 5-15P plug, a chrome safety grill, and mounting hardware. It ships as a 7.9 in x 6.6 in x 2.7 in (201 mm x 168 mm x 69 mm) assembly weighing 3 lbs (1.36 kg); the drawing shows the housing at 200.00 mm [7.874 in] by 168.00 mm [6.614 in] with an inner mounting panel and marked airflow direction.

This exhaust model is listed for use with the PFA30000 filter and is NWMFH2 compatible. Assembly to a PFA30000 uses #10-32 x 0.625 in panhead taptite Philips screws installed with a #2 drive Philips driver after removing and then reattaching the PFA30000 front filter grill. Fan components are UL 507 recognized and CSA certified, and the product is TAA, RoHS, and REACH compliant, manufactured in North America.
