The AHF series maximum flow air heaters are used with blowers or recirculating air in baking, drying, and preheating applications.
This air heater is designed with a 23/8' O.D. aluminum tube and a cross frame heating element for minimum resistance to air flow. The nickel-chrome heating element is insulated by ceramic beads on a stainless steel support frame which is firmly secured to the inside of the tube. Post terminals enclosed in a junction box simplify the wiring. A four-inch round flange with pre-drilled holes at the inlet side are used for mounting the heater. It has a practical operating range of up to 200 CFM with temperatures up to 600 °F (315°C).
Calculate the flow rate, temperature rise, or power requirement as follows:
Watts = SCFM x ΔT/3
SCFM = Standard Cubic Feet Per Minute
ΔT = Temperature Rise inDegrees F from the Inlet to the Outlet
Minimum flow rates are given in the table below.

| *These air heaters can be operated on either 120 or 240 Volts. Specifications are given for operation on both 120 and 240 Volts. **Indicates Watts per inch of heated length. Use the table above to determine minimum required flow rates. The Watts per inch of heated length can be changed by reducing the operating voltage or by ordering a custom made heater. Stainless steel construction also available. Consult Engineering. | ||

What size is the conduit knockout in the junction box?
The information for the knockout is not in any of the documentation but it is most likely a standard size used in electrical applications. If you need to know exactly send your question to temp@dwyeromega.com so it can be researched.

Can this unit be run using a DC power supply?
The AHF series heaters are rated for AC only. We offer 120 and 240 vac options.

Since it is sold in Canada, is it safe to assume that it is CSA or ULC approved?
Hi Sean_S
Thank you for the inquiry. Unfortunately the AHF heaters are not CSA or UL approved.
Best regards

I am making a low temp prepreg oven, I am curious if the AHF-10120 would be heat a area of between 27 to 48 cubic feet using a recirculating fan to about 350 to 400 degrees F.
Thank you for your inquiry. Please email you application requirements to heaters@omega.com and we will review and advise.
