Difference between Dry and Wet type Paint booths

What is the difference between a wet and dry paint booth?

A dry booth typically consists of paint arresting filters to trap the over spray paint or excess paint fumes.

A wet type  paint booth consists of a water curtain or water to trap the excess paint over spray which mixes and forms a sludge which is then treated and disposed off and the water can be reused once treated.

When will you use a wet booth over a dry paint booth?

Wet paint booth are used when there is high paint consumption and the paint arresting filters are not enough to trap the excess paint and filters will have to replaced frequently which can increase running costs.This is when a wet paint booth is used.

 

What is a Side Draft Paint booth?

Side draft paint booth is when the air flow is towards the water curtain or the paint arresting filter from the side. Generally making a civil pit will not be necessary in a side draft paint booth making it affordable and inexpensive.

When can you use a side draft paint booth?

Side draft paint booth is used when the component has to be painted only on one side or moving on a conveyor.Example automotive components, shock absorbers and some consumer products,

Special 3 axis platform which are pneumatic can be fitted inside the booth for better productivity and saves on repainting costs.

Symptoms Of A Bad Paint/Powder Drying Oven

How to know if your paint or powder curing oven is giving you issues? The paint curing oven is one of the most important part of your painting line and a bad curing oven can lead to a lot of risk and decreased productivity. Your curing oven should be able to satisfy all cure  parameters and perform consistently.

Some of the side effects or symptoms of  poorly designed paint curing oven are heat loss, chipping, poor airflow, orange peel, poor adhesion, difference in gloss, uneven colors/shade mismatching, poor chemical resistance, poor corrosion resistance etc. To avoid all these issues the paint curing oven must be designed properly with proper air flow and efficient heat exchangers (indirect heating). Prism ovens are well designed and known for their temperature accuracy. This is achieved through an effective air seal between the oven and the outside ambient conditions. Prism can supply various types of paint or powder curing ovens which include A Zone ovens, camel back ovens, ground mounted ovens and also IR ovens.
