Stop sacrificing indoor comfort for open-door access. This industrial air curtain delivers targeted airflow at commercial doorways to reduce energy loss, block pests, and maintain interior climate control while allowing staff and patrons to pass freely. Designed for 42-inch openings, the unit operates on 460v 3-Ph power and provides dependable, continuous performance in demanding service environments.
#@@# Unheated Design#@#
This unheated configuration directs uninterrupted airflow without additional electrical heat, reducing installation complexity and eliminating heat-related maintenance. Facilities that already control interior temperature with HVAC systems benefit from a focused air barrier that minimizes cross-contamination and energy transfer.
#@@# Optimized Width Coverage#@#
This model suits openings from 40 to 47 inches, centering performance on 42-inch doorways for consistent air velocity across the threshold. Kitchens, loading docks, and retail entrances gain uniform protection that prevents drafts and slows the ingress of outside air.
#@@# Motor Power#@#
The unit uses a single 1/2 HP motor rated at 510 watts and 0.8 amps at 460 volts, enabling strong, continuous airflow while remaining electrically efficient for three-phase systems. Operators can rely on predictable electrical draw for load planning in commercial electrical panels.
#@@# Durable Construction#@#
Engineers constructed the cabinet from galvanized steel with an obsidian black powder coat finish to resist corrosion and simplify cleaning routines. High-traffic locations benefit from a robust exterior that withstands routine exposure to grease, steam, and cleaning agents.
#@@# Performance Certification#@#
Certifiers validated the product with cETLus approval, confirming conformity with North American safety and performance standards. Facility managers can document compliance with codes and insurance requirements when specifying equipment for public or institutional buildings.
