Crossdraft Airflow Design
Crossdraft Spray Booth, which is a booth best for parts that require a basic finish quality. These booths can be designed to handle a wide variety of parts and for all different sizes. The term “crossdraft” refers to how the air travels through the booth, in this case, horizontally along the “cross-section” of the booth. It can be defined as a booth where air passes from the front of the booth (sometimes through supply filters) and then horizontally towards the booth’s rear exhaust chamber. This horizontal flow causes air to flow uniformly over the painted part as it enters an exhaust filter chamber. The exhaust chamber incorporates the exhaust filters so the air can be filtered from any paint overspray as it passes through the filters. The clean air is pulled by the exhaust fan through these filters and exhaust duct system as it is discharged cleanly into the atmosphere.
Air enters through the front of the booth, then through the intake filters. As the air passes through the filters, where containments are captured. This is accomplished without sacrificing the quality or volume of the airflow itself
After passing through the filters, the air is a particle and dust-free. This creates a virtually clean environment. This clean air passes through the booth resulting in controlled and even airflow.
As the air flows over the product being sprayed, overspray is being suspended, thus carrying it to the exhaust filters.
The exhaust filters are designed to hold more paint. They are made from a continuous filament glass fiber with an open weave pattern. This design prevents face-loading as they become saturated. This design forces paint-laden air to change direction many times as it passes through the filter preventing fogging.
This clean air now continues through the exhaust plenum, which is designed to balance airflow throughout the entire booth.
To have the best possible airflow, Spray Systems precisely matches the size of the motor and fan assembly, to each booth. These assemblies operate at noise levels below OSHA limits.
