Dry Filter Spray Booth VS Water Wash Spray Booth

There are numerous differences between dry filter spray booth & water wash spray booth, which is the better choice is depending on their intended use.

What is Water Wash Spray Booth?

Paint overspray is collected and arrested in the water curtain or scrubber section of the booth. This interaction is critical to properly remove the paint overspray from the air and put it into the water. The waste paint is then dropped down into a tank. The collection tank finally becomes filled with paint sludge that needs to be cleaned.

Water curtain spray booths supports for large volume paint application or continuous production rates, which handles significantly more overspray than dry filter booth. It is built for safe, health and fireproofing codes as well.

What is Dry Filter Spray Booth？

Dry filter booths use layered filters to separate the paint particulate from the constant airstream passing through the exhaust filter, ensures only free of particle air vent to the atmosphere.

This type of spray booth is generally recommended for low to medium-level production volume operations.

Dry Filter Spray Booth Advantages & Disadvantages

Advantages

• Lower initial equipment costs, it is much cheaper than water wash booth.

• Installation, operation is easier as compared to a water wash booth

Disadvantages

• Dry filter booth is hard to handle high volume production

• The filters have relatively short service life and must be replaced regularly to ensure effective collection. Thus the subsequent recurring cost of filter replacements is required.

Water Wash Spray Booth Advantages & Disadvantages

Advantages

• Flexibly supports various scale applications, specially for high production rates

• Without need of replace filters that reduces downtime and ensures efficiency.

• Much cleaner and safer waste removing system

Disadvantages

• Higher initial booth equipment cost

• Paint overspray is trapped into a collection tank, the sludge should be cleaned periodically.

Choosing of applying a dry filter spray booth or water wash spray booth mainly is mainly taken refer to your scale of production rate, vast small and medium spraying jobs in the industrial utilize dry filter booth system, while water wash booths is justified with high production rates, also operation or environment or other factors would be taken into consideration.
