Create an invisible barrier over your door with Maxwell MASF series. Adopting the highest
technology in aerodynamics, all Maxwell Air Curtains run smoothly with low noise. MASF Series
Air Curtain by Maxwell boasts a streamlined modern appearance with no visible exterior screws.
Features stainless cover constructed of durable aluminum as attached mounting plate. They are
ideal for any location where you would like to create an invisible barrier to dust, insects, and
pollution. The powerful airflow divides the inside and outside environments into two independent
temperature zones. This minimizes air conditioned/heated air losses through opened doorways
and areas with doors that are constantly opening and closing. Easy to adjust with directional airflow louver and convenient two-speed hi-lo fan operation controlled by a unit surface mount
switch. The air curtain uses ambient air and is NOT an air conditioner.
Includes: 36” air curtain, door switch, installation hardware, 5 ft. power cord with grounded NEMA
5-15 plug, user's manual, installation manual, manufacturer warranty.

3.1 Please install air curtain in a sturdy and secure
place to avoid instability that can cause injury and
damage to your air curtain unit.
3.2 Please install the unit inside and not outdoors,
for best efficiency.
3.3 Install air curtain unit between 7 to 9 ft. from
the ground.
3.4 When the entrance is wider than the unit, it is
recommended to install two or more units in
parallel. In this case, provide 20-40mm gaps
between the units.

C) Installing from the ceiling:
(Note: this installation is NOT recommended; the ceiling brackets are not supplied)
4.3.1 Remove the attached mounting plate by
removing the fixed screws on the back of the
main body.
4.3.2 Securely mount the ceiling brackets (not
