72-Inch Heated Low-Profile Air Curtain

This heated air curtain spans 72 inches wide with an 8-inch height and 12-inch depth. It delivers a maximum air velocity of 1,800 fpm and 1,800 cfm volume for temperature control up to 8 feet mounting height. The unit operates on 208V single-phase power with a 23-degree Fahrenheit temperature rise.

Replaces Open Doorways for Climate Separation

The curtain creates an invisible barrier that reduces heat loss through open frame openings up to 6 feet wide. It is worth installing when insect control is needed at 7 feet mounting height or when conditioned air retention matters. The 53 dBA sound level at 10 feet suits commercial entrances where noise must stay moderate.

Single-Phase 208V Installation Limits

The 208V single-phase requirement restricts use to sites with compatible electrical service. Black steel housing weighs 79 pounds and needs secure mounting across the 72-inch width. Low-profile design fits tight header spaces but still demands 12 inches of depth clearance for proper airflow projection.

Questions about this item

What mounting height and opening width does the LPV272-1EBF-OB require for temperature control?

The unit is designed for a 6 ft frame opening width and a maximum mounting height of 8 ft for temperature control applications.

What electrical supply is needed for the 208V single-phase heater and how is it wired?

The air curtain requires a 208V AC single-phase connection; power wiring must be run to the internal junction box inside the steel housing.

How often should the intake screen be cleaned to maintain the 1,800 cfm airflow?

Clean the intake screen monthly or whenever visible dust builds up, because restricted airflow reduces the 1,800 cfm rating and the 23 °F temperature rise.
