Ventilation & Make-Up Air

Exhaust fans, make-up air units, and fresh air supply equipment — King Electric make-up air unit heaters, Rupp direct gas-fired make-up air units, and Canarm/Delhi Blowers filtered fresh air supply units.

Special order. These are full replacement units, not stocked parts — every listing here ships special order at zero on-hand inventory. Contact us for current lead time and a freight quote before ordering. Pricing shown is current market plus our markup, not a discount.

Built for the trade. This catalog is for licensed HVAC contractors, mechanical engineers, and property/facilities teams sourcing replacement ventilation and make-up air equipment — not a DIY install.
