Water Wash Spraybooth
When a Dry Filter Spray Booth is not suitable because of the nature of the materials to be applied, or due to the requirement to improve the efficiency of the extraction system, our Water Wash Spray Booths provide the perfect solution, utilising the latest nozzle and weir technology to meet improved extraction criteria.
The Hi-Tec Water Wash Spray Booth is designed to provide increased overspray capture by means of its unique high pressure scrubbing action and delivers the perfect solution to these improved extraction requirements.
All our Water Wash Spray Booths are supplied as standard with a 1,000 mm working depth, 2,250 mm working height, fan, fan starter, pump and pump starter.
Standard Water Wash booths are of the pump and nozzle type, with flooded rear curtain (304 grade stainless steel) and have hard faced mechanical pump seals as standard.
The standard fan is suitable for a vertical run of ducting with no more than one 90° bend. If more than one 90° bend is necessary then the fan may require up-rating.
All spraybooths will require ducting to atmosphere, for further information and a quotation please contact us.
All spraybooths will arrive 'flat packed' and will require assembly. If you choose to purchase ducting this will need to be cut, fitted and sealed to suit your application. The straight spiral ducting is supplied in 3m lengths. One length of 3m spiral ducting is included in all the ducting options with the exception of Option 9, additional lengths and couplers are available on request. If the ducting is not purchased all booths will come with a spigot flange adapter to enable you to fit standard ducting at the size detailed in the product specification
The Theory
Overspray is drawn through the water curtain and into the wash plenum where it is scrubbed. This scrubbing action is created by means of high pressure nozzles. The air then passes through a series of baffles to remove the excess water and is then expelled into the atmosphere.

Ducting
The Environmental Protection Act states that extract ductwork from a spraybooth should discharge in a vertical direction and goes on to say "In order to ensure dispersion is not impaired by either low exit velocity at the point of discharge, or deflection of the discharge, a cap, or other restriction, should not be used at the stack exit".
We would, therefore not recommend a horizontal discharge, however it can be supplied on the understanding that you (the client) take full responsibility for this choice and have carried out your own risk assessments.
