Introducing the COMBI®, Featuring a 3-speed motor.
This unheated air curtain is of unparalleled performance.
Just set the speed to match the application and the
COMBI does the rest. At customer entrances, the
COMBI creates a living curtain of air virtually undetected
by customers walking through the doorway.
Adjustable Air Directional Vanes Provide Draft Control

Adjustable vanes at the outlet nozzle can be positioned
to direct air where needed and can be easily set to
compensate for possible draft conditions through open
doorways. The adjustment range is 40 degrees front to
back.

Multiple speed motors available in single phase only
115v or 230v. (1/2 HP in 3-speed, 1 HP in 2-speed).
Heavy Duty Electric Motors Designed for Long Life
All our air curtains use a continuous heavy duty type
motor engineered for many years of maintenance-free
operation. These UL Listed motors contain lifetime-
lubricated, double-sealed ball bearings. The motors are
totally enclosed, resilient mounted and protected by an
automatic thermal overload switch. All motors have one
second start to full capacity.
High Velocity, Quieter Sounding Air Curtain
The COMBI is actually quieter than conventional units even though the air velocity is higher, thanks to a new high-tech, specifically formulated material called PolyMars®. Our air curtains are quieter than OSHA standards and has lower sound levels than any other similar units in the industry.
Fire Retardant and Corrosion Proof
Any Customer Color Available Cabinets of all our air curtains are manufactured of one
piece molded white PolyMars® material. They are
resistant to high humidity and all chemicals and climatic
exposure. Our air doors are now UL listed for both
indoor and outdoor installations.
We can match the color of your interior or exterior
mounting surface and guarantee that the color will never
fade or peel since it is molded into the PolyMars cabinet.
Easy to Install
All our air curtains are easy to install. Just use three fasteners to attach the units to the wall. Then connect electric power to the unit's junction box(s) through the 1/2 inch conduit fitting(s). One watertight electrical junction box per motor is provided. Junction box is mounted on the bottom center of each motor/fan assembly. Three speed selector switch is shipped loose for wall mount. Units Can Be Used in Multiples for Wide Doorways
For wider doorways, units can be mounted side-by-side in multiples, if necessary, air curtains can be spaced up to six inches apart.
