the product described. Protect yourself and others by observing all safety information. Failure to comply with these
instructions could result in personal injury and/or property damage. Retain these instructions for future reference.
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

Customer Entrances) models (Flying Insect Control up to
7’) and LPN2-F (ETL Sanitation for Counter Top/Pass
Through Windows) models (Flying Insect Control up to 4’
from Counter Top) All ETL Sanitation Certified Models
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. The units are ETL Listed,
Canada and US, for either an inside or outside mount and
ETL Sanitation Certified. Heated units must be mounted
on the inside or the protected side of the opening. The
motors used in all LoPro Series are 1/6HP.
The LoPro Series come standard with a stamped air
intake screen(s). The LPV2 models can be configured
with an aluminum mesh filter(s) as an option. The LPN2
models 25” and all LPN-F models come standard with an
aluminum mesh air intake filter(s) in conjunction with the
punched air intake screen(s).
