TJERNLUND

TJERNLUND is a manufacturer of combustion air and venting systems, primarily serving the HVAC and industrial heating markets. Founded in the United States, the company has a long history of producing draft inducers, combustion air intake systems, and related controls for gas- and oil-fired equipment. Their product line includes pipe-mount and roof-mount exhaust draft inducers, inline duct fans for radon mitigation, vent hoods, blower wheels, speed controls, and air pressure switches. These components are designed to ensure proper venting and combustion air supply for furnaces, boilers, water heaters, and other heating appliances. TJERNLUND products are built to recognized safety standards, with many units carrying ETL or cETL listings, indicating compliance with North American safety requirements. The company focuses on practical engineering: their draft inducers are available in various pipe sizes (4 in to 10 in), voltage configurations (115V AC, 120V AC), and include features such as stainless steel wheels, fan proving switches, and universal controls. The GPAK1, for example, is a pipe-mount draft inducer for natural gas furnaces, rated at 1.26 A and including a draft control. The RT750 is a roof-mount unit for furnaces and oil heating, handling 8 in to 10 in pipe with a stainless steel wheel and a fan proving switch. The HS2 is designed for water heaters using LP fuel, with a UC1 Universal Control and a flow rating of 286 cfm at 0.0 in static pressure. Beyond draft inducers, TJERNLUND supplies accessories such as the VH1-6 vent hood (6 in duct, aluminum, with screen), the AS2SW3 dial fan speed control for the AireShare series (24V AC, steel plate), and the PS2501 adjustable air pressure switch (0.05 in wc to 12 in wc, SPDT, 115V AC). The company also offers replacement parts like the 950-1011 forward-curved blower wheel (3 3/4 in diameter, steel). For radon mitigation, the PVC4 inline duct fan (4 in duct, 80 cfm max, 115V AC, PVC housing) provides a dedicated solution. 3G Electric stocks over 100 TJERNLUND SKUs, providing datasheets and logistics support for global procurement. Engineers and maintenance managers can specify these components for new installations or retrofits, relying on consistent performance and adherence to industry standards.

Frequently asked questions

Common questions about TJERNLUND from 3G Electric.

What is the typical application for the TJERNLUND GPAK1 draft inducer?

The TJERNLUND GPAK1 is a pipe-mount exhaust draft inducer designed for natural gas furnaces. It operates on 115V AC with a current draw of 1.26 A and includes a draft control. This ETL Listed unit is intended to improve venting efficiency by creating a consistent draft, reducing the risk of backdrafting or incomplete combustion. It is suitable for residential or light commercial furnace installations where the vent pipe is 4 inches in diameter.

Does the TJERNLUND RT750 roof-mount draft inducer include a fan proving switch?

Yes, the TJERNLUND RT750 roof-mount exhaust draft inducer includes a fan proving switch. This switch monitors airflow and ensures the inducer is operating before the burner can fire, enhancing safety. The unit is designed for furnaces and oil heating, handling 8 in to 10 in pipe, and features a stainless steel wheel. It operates at 115V AC (nameplate 120V AC) with a current draw of 1.2 A and is cETL Listed.

What control is included with the TJERNLUND HS2 draft inducer for water heaters?

The TJERNLUND HS2 pipe-mount exhaust draft inducer includes a UC1 Universal Control. This control allows for flexible installation and integration with various water heater systems. The HS2 is designed for water heaters using LP fuel, operates on 115V AC with a current draw of 1.51 A, and is cETL Listed. It handles 6 in to 8 in pipe and delivers 286 cfm at 0.0 in static pressure.

Is the TJERNLUND PVC4 radon fan speed controllable?

No, the TJERNLUND PVC4 radon inline duct fan is not speed controllable. It is a single-speed unit designed for radon mitigation applications. The fan has a maximum airflow of 80 cfm, operates on 115V AC, and features a PVC housing. It includes a 6 ft power cord and is intended for 4-inch ductwork. The motor is high-efficiency but fixed-speed, so it runs at full capacity when powered.

What is the adjustment range of the TJERNLUND PS2501 air pressure switch?

The TJERNLUND PS2501 is an adjustable set-point air pressure switch with a range of 0.05 in wc to 12 in wc. It features auto reset and is housed in a conduit box. The switch is SPDT and rated for 115V AC. This makes it suitable for monitoring draft or airflow in HVAC systems, providing a signal when pressure thresholds are met or exceeded.

What material is the TJERNLUND VH1-6 vent hood made of?

The TJERNLUND VH1-6 vent hood is made of 5052 aluminum with a silver finish. It is a round wall cap designed for 6-inch ductwork. The hood includes a screen to prevent debris entry but does not include a backdraft damper. Connection is via press fit, and the material thickness is 20 ga. This vent hood is suitable for exhaust terminations in residential or commercial venting systems.
