NuMax Air Powered Operator
Designed for wet, corrosive, high-use environments
Designed with your toughest environment in mind, NuMax Air-Powered Door Operators are ideal for any application where dependability, reliability, and durability are absolutely critical for a profitable and trouble-free operation. Utilizing an innovative compressed-air and rare-earth magnetic design, NuMax operators feature a heavy-duty, rust-resistant build.
Air power changes the failure math in a wet bay. With no electric motor hanging in the spray path, the most vulnerable part of a conventional operator simply is not there. The compressed-air drive runs on the shop air you already have, the rare-earth magnetic design delivers clean, repeatable motion cycle after cycle, and the field-serviceable build means your own maintenance staff can keep it running.
Why It Works
- Compressed-air drive. No electric motor exposed to moisture.
- Rare-earth magnetic design for clean, repeatable motion.
- Heavy-duty rust-resistant construction.
- Engineered for wet, corrosive, high-use environments.
- Field-serviceable by your own maintenance team.
- Drawbar mounted above the door where it is warmer and drier.
- Direct connection to the door ends the cable jumping that plagues jackshaft openers.
- Backed by a 36-month warranty.

Engineered for the Environment
- Air-Powered Drive
- Runs on shop air, keeping electric components out of the wet zone entirely.
- Magnetically Coupled Cylinder
- A heavy-duty, rust-resistant tubular cylinder with no mechanical connection between the piston and the piston slide. The magnetic coupling removes the need for external seals and cuts the number of wear components, which is what makes the operator leak-proof and low maintenance.
- Built for Cold Mornings
- The exhaust-only configuration lowers the probability of moisture intake and freeze-ups, so the door still cycles in January.
- No Cable Jumping
- NuMax connects directly to the door, which takes out the downtime caused by cable jumping common with jackshaft style openers.
- Serviceable In Place
- The field serviceable design lets your own crew replace seals and other repair components on site. No sending the unit back to the factory.
- Watertight Controls
- A NEMA-4X watertight control box handles photoeyes, loops, timers, radio controls, contact switches, relays, and proximity switches. High-quality valve, filter, regulator, OSHA cut-off valve, and double-sealed push buttons are included, with an emergency open button or thermostat optional.

Wet bay? Put the electronics somewhere else.
If your facility already runs compressed air, NuMax is often the most dependable operator you can hang, and it integrates easily with car wash and other equipment. Send us the door size and your air supply details and we will confirm the fit.
