This anodized aluminum unheated air curtain combines targeted airflow with industrial duty components to maintain temperature differentials and reduce infiltration in high traffic openings. Designed for 42 inch door spans, this unit supports 8 Ft. opening heights and operates on 208-230v 60 Hz three phase power for robust, continuous performance.
LongDescription#@#NA#@@#Cleaning Instructions#@#Use a soft cloth and mild detergent to wipe the anodized aluminum cabinet and grille, avoiding abrasive pads. Spray sanitizer on cloth, then treat high-touch zones like door frames, control switches, and nearby menus; allow contact time per label. Rinse residue with clean water and dry to prevent corrosion. Clean weekly or after spills to deter pests, maintain appearance, and reduce germ transfer between front‑ and back‑of‑house.#@@#Additional Info#@#Mars Air Systems QP1042-1UG-AL is a 42" unheated QuietPro air curtain in anodized aluminum. It has a 1/2 HP motor, 208/230v 60 Hz 3-Ph power, ETL sanitation listing, and is effective for 40"-47" openings up to 8 Ft. It weighs 65 pounds.#@@#General Info#@#Description #@#
This anodized aluminum unheated air curtain combines targeted airflow with industrial duty components to maintain temperature differentials and reduce infiltration in high traffic openings. Designed for 42 inch door spans, this unit supports 8 Ft. opening heights and operates on 208-230v 60 Hz three phase power for robust, continuous performance.
A single 1/2 HP motor delivers concentrated airflow to form a stable air barrier across 40 inch to 47 inch openings. This motor configuration minimizes gusting while providing reliable runtime for facilities that run extended hours.
Engineered for 208-230 volts 3-Ph systems, the unit integrates cleanly into standard commercial electrical infrastructure. Installers will appreciate consistent voltage range and 60 Hz operation that matches common utility supplies.
Anodized aluminum cabinet provides corrosion resistance and a serviceable surface that cleans easily without specialty solvents. Maintenance teams will notice lower long term degradation compared with painted steel finishes.
Calibrated for doors up to 8 Ft. in height, the curtain produces an effective laminar flow that reduces conditioned air loss and limits ingress of dust and exhaust. Operations that require strict indoor climate control will see measurable improvements in thermal retention.
ETL sanitation listing confirms compliance with recognized safety standards for commercial installations. Facility managers gain documentation to satisfy inspection and insurance requirements.
At approximately 65 pounds, the unit balances sturdy build with manageable handling for two technicians during mounting and servicing. Removable panels grant direct access to motor and internal components, reducing downtime for routine checks and repairs.
