Exhaust fans, make-up air units, process ventilation. The unglamorous stuff that keeps your warehouse breathable, your plant properly ventilated, and your tenants from complaining about the smell from unit 7.
CaptiveAire, Cambridge, Accurax, EcoAir. Belt drives, direct drives, motor replacement, damper actuators, weather hoods.
Tempered make-up air for warehouses, manufacturing, and process spaces. Heat section service, filter banks, VFD-driven fans.
Welding fume, paint booth, plating, woodworking. Ductwork repair and fan service. Coordinate with your industrial hygienist on capture velocities when you need it.
Configuration, troubleshooting, and replacement when the drive finally lets go.
We come out and trace the system end-to-end. Photo documentation of any issues we spot along the way.
Amp draw on the motor, static pressure across filters, capture velocity at the hood. Numbers, not guesses.
Most fan and MAU work is straightforward. For larger jobs you get a written quote with options and trade-offs.
Re-measure airflow, amp draw, and static pressure after the repair. You see the before/after numbers.
Usually one of three things: a bearing that's seizing, a belt that's over-tensioned, or a contactor that's welding closed and re-starting. We'll measure amp draw under load and find out which one.
We service and maintain the equipment that supports whatever spec you're working to. Your engineer, industrial hygienist, or safety consultant defines the targets — we make the equipment hit those numbers and stay there.
For most direct-replacement jobs, yes — we re-use the existing curb. If the curb is rotted or the new unit needs a different footprint, we coordinate with a roofer up front so it's one trip, not three.
Exhaust fans, make-up air, dining-room comfort. Code-passing work, scheduled around your hours.
