Dry Filter Spray Booths

The reverse jet filter is designed to collect paint particulate after dry powder coating. The jet mechanism fires a reverse thrust of air back through the spray booth filter to dislodge stuck particulate and drop it into the waiting hopper below ready for waste disposal.

A spray booth is a bespoke product and in general is dictated by a range of variable factors such as , size of company, volume of spraying, building regulations attached to the facility to name just a few. It is possible to build spray booths such as bench booths for as little as £2000+ on a supply only basis and full turnkey designed spray booth, flash room and drying operation can reach over £1million pounds plus. It depends on the nature of the requirement so get in touch if you need further information.

Centrifugal spray booths, apart from being quiet, reliable and extremely versatile in terms of operational conditions, also accumulate less overspray. This means that noise is reduced, and there’s less of a need for constant maintenance.

There are a number of different types of spray booths, each designed to fulfill a range of applications. Here are a few of the most utilised: • Bench type spray booths – bench booths are designed for finishing specific spray jobs with flexibility and ease at bench height • Dry filter spray booths – dry filter booths use layered filters to separate particulate from the air passing through the exhaust • Water wash spray booths – water wash spray booths trap paint overspray and particulate with curtains of water, deposit this by-product into collection tanks • Crossdraft booths – during a spray job, crossdraft booths bring air into the front of the booth, and expel it out the rear as an airstream • Downdraft booths – produce draft patterns that fall from the ceiling to the floor, and are then expelled underneath the booth

Dry filter spray booths use layered filters to capture paint particulates, effectively separating them from the air moving through the exhaust system of the booth. Water wash booths perform the same task but use a water curtain to trap overspray, separating it from the moving air. This paint particulate is then dropped into a collection tank.

Here are the key benefits and features of a dry filter booth: • Low-cost filters • Low-cost maintenance • Top or rear-mounted fans • Reduced need for extra cleaning caused by overspray • Meets all health and safety code compliances

Low-level extraction boxes are used in spray booths, paint shops, and other industrial environments affected by overspray and VOCs like acetone and formaldehyde.

There are many types of spray booth and drying room to choose from. Designs can be dictated by budget, production requirements or even health and safety and building regulations. Check out our video link for help on Which Spray Booth To Buy? https://youtu.be/vaCfdEH528c

Every two to four weeks. Depends on amount of paint volume being sprayed but two to four weeks is a good gauge for most dry filter spray booths

As with disadvantages associated with many other booths, for the centrifugal spray booth, they’re usually related to specific processes and volume. Dry filter systems like the centrifugal booth can struggle to handle high production volumes and may not be able to filter some kinds of compounds in certain paints. What’s more, because filters in these booths have to be regularly replaced, they can be somewhat of an added expense.

There are two particular hazards associated with most spray booths: • Chemicals and toxins – these are the by-products from the spraying process, but are usually effectively removed through the centrifugal filtration system • Fire and explosions – some of these same chemicals and toxins are flammable, and so can sometimes react in a volatile way, if proper safety measures aren’t maintained

Your centrifugal spray booth is no doubt a crucial part of your business. If it breaks down, the very driving force that is your production line, can come to a grinding halt. To prevent this, there are a few checks you can make, to ensure you’re not caught off-guard: • Keep your booth clean • Change your dry filters on a regular basis • Check the seals on doors and openings to ensure contaminated air stays out • Establish a regular maintenance plan – one that’s conducted by professionals - and stick to it

Airflow in a centrifugal spray booth is a vital safety requirement set in place to reduce the concentration of flammable material and particulate in a booth. Airflow is measured in linear feet per minute (LFM) – a measure that’s usually calculated first in an empty booth, with a cross-sectioned area of the airflow direction. According to the International Fire Code (IFC), a spray booth needs 100 linear feet per minute to meet minimum requirements.

There are a number of benefits a bench type spray booth lends to your production line. These benefits include: • Unmatched control over hazardous material in the workplace • Improved quality of work – the controlled environment enables ease and flexibility in all spraying work • A bench type spray booth ensures cleanliness at all times in a workspace – contaminants and pollutants are easily prevented from compromising the quality of a spray or coating job

There are a number of industries that may benefit from the application of a bench type spray booth. These include: • Industrial manufacturing • Aerospace • Aviation • Automotive • Large equipment fabrication

There are some disadvantages to keep in mind, when considering incorporating a bench type spray booth into your workshop assembly line. These can include: • Filters need to be regularly replaced, which can be costly • The bench type spray booth is a dry filter unit, and so may need higher wind pressure - this could increase the consumption of paint • Bench type spray booths may need more maintenance, and more cleaning work after every use

Cleaning your booth will depend on the frequency of use, and the type of spraying and coating work done. However, the nature of this kind of work, is that it’s always going to be messy. So, a thorough clean should be done on your booth on a weekly to monthly basis, to remove overspray and particulate, and keep it functioning optimally.
