OVERVIEW

Mars Air Curtains are

designed to cover door

openings, providing both

temperature

control/environmental

separation and flying insect

control, when the building’s

doors are opened. Typical

installation heights are:

Standard 2 Series

(Environmental up to 10’,

Flying Insect Control up to 8’),

High Velocity 2 Series

(Environmental up to 12’,

Flying Insect Control up to 10’), and Extra Power 2

Series (Environmental up to 16’, Flying Insect Control

up to 14’). All ETL Sanitation Certified Series should be

mounted at the Flying Insect Control heights referenced

above. The units are typically wall mounted horizontally

above the door opening. They can also be suspended

from the ceiling or vertically mounted along side the

opening. The units are ETL Listed for either an inside

or outside mount. Heated units must be mounted on

the inside or the protected side of the opening. The

motors used in the Standard 2, High Velocity 2 and

Extra Power 2 Series are 1/2HP, 1HP and 3HP

respectively. The ETL Sanitation Series utilizes 1/2HP

and 1HP motors.

The Standard 2, High Velocity 2 and Extra Power 2

Series come standard with an air intake grille. They can

also be configured with an aluminum mesh air intake

filter instead of the air intake grille or in conjunction with

it.
