Stop losing conditioned indoor air to exterior drafts. This industrial air curtain creates a controlled air barrier that reduces infiltration, maintains interior temperature, and lowers HVAC load for high-traffic openings. Designed for commercial doors up to 47 inches wide, the unit combines proven airflow engineering with robust cabinet construction for continuous operation.
LongDescription#@#NA#@@#Cleaning Instructions#@#Wipe the air curtain housing and mounting brackets with a mild detergent and a soft cloth; rinse and dry. Sanitize high-touch covers, switches, and nearby door handles with EPA-approved disinfectant on a regular schedule. Vacuum intake grille monthly to prevent debris buildup. Check and tighten mounting hardware quarterly. Cleaning prevents cross-contamination between front- and back-of-house, supports health-code compliance, deters pests, and preserves finishes and service life.#@@#Additional Info#@#Mars Air Systems STD242-1UD-OB air curtain fits 42" openings, operates unheated on 208-230v, 60 Hz, 1-Ph with a 1/2 HP motor drawing 2.5 amps; galvanized steel cabinet with black powder coat finish, cETLus certified, 65 pounds.#@@#General Info#@#Description #@#
Stop losing conditioned indoor air to exterior drafts. This industrial air curtain creates a controlled air barrier that reduces infiltration, maintains interior temperature, and lowers HVAC load for high-traffic openings. Designed for commercial doors up to 47 inches wide, the unit combines proven airflow engineering with robust cabinet construction for continuous operation.
#@@# Cabinet Construction#@#
The galvanized steel cabinet features an obsidian black powder coat finish that resists corrosion and withstands daily use in demanding environments. Engineers designed the enclosure for straightforward wall mounting and access, enabling fast inspection and maintenance without disrupting service.
#@@# Airflow Capacity#@#
Engineers sized the unit for door widths from 40 inches to 47 inches and for openings up to 12 feet high, delivering focused, laminar flow that minimizes cross drafts and the entry of exterior contaminants. Technicians can rely on consistent performance across typical commercial thresholds.
#@@# Motor Performance#@#
The assembly uses a single 1/2 HP motor rated at 510 watts and drawing 2.5 amps at 208-230 volts, 60 hertz, single phase, providing sustained thrust and long service life. Operators receive dependable airflow while electrical demand remains predictable for facility power planning.
#@@# Energy and Certification#@#
The unit operates on 208-230 volts, 60 hertz, 1-Ph power and carries cETLus certification, confirming compliance with North American safety standards. Facility managers benefit from documented safety and reduced compliance risk during inspections.
#@@# Serviceability#@#
Technicians access internal components through removable panels and a simple mounting arrangement, which reduces downtime during routine service or motor replacement. The modular motor and fan assembly simplifies parts replacement and lowers life-cycle maintenance costs.
