#@@# Motor Efficiency#@#
A single 1/2 HP motor provides focused, reliable airflow while consuming 550 watts at 2.5 amps, delivering performance optimized for heavy foot traffic openings. Installers will appreciate the straightforward electrical requirements of 208-230 volts 60 hertz 1-Ph, simplifying wiring and reducing installation time.
#@@# Durable Cabinet#@#
Galvanized steel construction with an obsidian black powder coat resists corrosion and daily wear in demanding environments. Facility managers benefit from a finish that maintains appearance and protects structural components in food service and institutional settings.
#@@# Coverage Range#@#
Engineers designed the air stream for a 48-inch nominal door width and effective use on openings up to 12 feet high, enabling a single unit to serve standard storefronts, kitchen pass-throughs, and service entrances. Operators can expect consistent air separation across the full opening to limit the transfer of air and particulates.
#@@# Safety Certification#@#
The unit carries cETLus certification, confirming compliance with applicable North American electrical and safety standards. Maintenance teams gain confidence in certified components and clear labeling for inspection and safety audits.
#@@# Compact Footprint#@#
Measuring approximately 12.13 inches in height and 12.75 inches in depth, the curtain fits into tight header spaces without protruding into walkways.
