Cross draft means diagonally open windows that maximizes fresh air in ALL rooms and on all floors.
What is a down draft spray booth? In a downdraft booth, the air creates an envelope around the car. The air is drawn down, and over the vehicle, excess overspray is carried into the pits, through a series of filters before being exhausted to the atmosphere. Full downdraft paint booths require a pit for the airflow path.
What is a semi down draft spray booth? The semi-downdraft booth is a hybrid, combining features of both crossdraft and downdraft booths. Air is introduced into semi-downdraft paint booths through the ceiling in the first 25 to 30 percent of the booth.
What is the airflow for a spray booth? Airflow in a semi-downdraft booth is a true combination of horizontal and vertical. Flow originates from the ceiling of the booth, usually from a supply unit located near the front. The air passes diagonally downwards, is drawn across and exits the booth through the base of the walls or rear.
How does a semi-downdraft spray booth work? The semi-downdraft design achieves the benefits of a downdraft booth by pressurizing the air through a supply plenum that is typically located near the front of the booth. The pressurized fresh air is released from the top of the booth, then flows diagonally across and down towards the rear of the booth enclosure.
Which type of spray booth is the most popular air movement system used today? Downdraft paint spray booths have become the accepted standard in the automotive refinishing industry and are becoming increasingly popular in industrial applications as well.

How does a paint booth work?
A paint booth works by manipulating the principles of negative and positive air pressure. Spray painting booth ventilation relies on the balance of the exhaust fan and the air replacement fan. If just the exhaust fan is on, the booth takes on negative pressure, since more air is being removed than pushed in.
How much airflow does a spray booth need?
Reply: Table G-10 of 1910.94(c)(6)(i) specifies the required airflow velocities ranging from 50 to 250 linear foot per minute (fpm) into the openings of a spray booth for various operations and designs, except where a spray booth has an adequate air replacement system.

Which of these types of airflow does a downdraft spray booth provide?
3. Downdraft Booths. Downdraft booths indisputably have the best airflow style for controlling overspray and contamination. Like side downdraft booths, uniform airflow is achieved through a full-length, filtered ceiling and exhaust pit that runs nearly the entire length of the booth.
