OVERVIEW 

 

Mars Air Curtains are

insect control, when 

the building’s doors 

are opened.  Typical 

installation heights 

are: LoPro Series; LPV2  (Variable Speed) models 

(Environmental up to 8’), LPN2  (ETL Sanitation  for 

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.

intake screen(s). The LPV2  models can be configured 

with an aluminum mesh filter(s) as an option. The LPN2
