Hammond: Thermostat-Controlled Rack Cabinet Fan Kits – DTFK Series

September 16, 2026
DTFK Series: An Ideal Solution for Industrial Automation, Networking, Telecommunications & Edge Computing Applications
The DTFK Series Thermostat-Controlled Fan Kits provide intelligent cooling for rack cabinets and industrial enclosures by operating only when additional airflow is required. An integrated adjustable thermostat automatically activates the fan as enclosure temperatures rise and shuts it off once the desired temperature is restored. This helps protect sensitive electronics while reducing energy consumption, noise, and unnecessary fan wear.
Available in both intake and exhaust configurations with airflow up to 550 CFM, the DTFK Series is ideal for industrial automation, networking, telecommunications, and edge computing applications. Designed for Hammond filtered enclosures and compatible with many products featuring the standard 4.7-inch fan pattern, these kits offer an easy way to improve thermal management without continuous fan operation.
Features
- Heavy-duty AC cooling fans with integrated thermostat automatically switch on and off based on enclosure temperature, helping maintain safe operating conditions while reducing unnecessary fan operation.
- Adjustable thermostat controls temperatures from 32°F to 140°F (0°C to 60°C), allowing cooling to match your application.
- Available as exhaust and intake fan configurations to support different airflow strategies and enclosure layouts. Airflow ranges from 105 CFM to 550 CFM, depending on the model.
- Designed for Hammond NWC Type 12 Filtered and selected NWM enclosures, while compatible with many Hammond products using the standard 4.7-inch fan opening. Additional mounting hardware is included where required.
- Complete kit includes the fan, integrated thermostat, 6-foot power cord, chrome safety grill, and mounting hardware for fast installation.
- Reduces continuous fan operation, helping decrease noise, energy consumption, and fan wear compared to continuously running cooling systems.
- Fan components are UL 507 recognized, and CSA certified for dependable operation.
- Operating temperature range of -20°C to +60°C with 5% to 95% non-condensing humidity.
- Decibel (db) rating is measured at 12” to 24” from the source.
- TAA compliant, RoHS compliant, and REACH compliant. Manufactured in North America.
