Selecting a spray booth is not simply a matter of choosing the largest fan or the biggest booth available.
The booth needs to control airflow, overspray, filtration, exhaust, operator exposure, fire safety and maintenance requirements according to the coating process.
Two common approaches for industrial applications are water curtain / water-wash booths and dry cartridge filtration booths.
Water Curtain Spray Booth
A water curtain booth uses a controlled water film to capture overspray.
Advantages
- Suitable for high overspray applications
- Water captures coating particles
- Can handle significant paint loading
- Suitable for large industrial products
- Overspray can be collected in a water system
- Useful where wet collection is preferred
Considerations
- Requires water management
- Sludge must be removed
- Pump and water circulation require maintenance
- Wastewater management must be considered
- Higher water consumption than dry filtration
Cartridge Filtration Booth
A cartridge booth uses dry filter cartridges to capture overspray.
Advantages
- No process-water circulation
- Lower water consumption
- Compact system
- Easy modular expansion
- Cartridge replacement is straightforward
- Suitable for many industrial coating applications
Considerations
- Filter loading must be monitored
- Cartridge selection is important
- Filters require replacement or cleaning
- Overspray characteristics must be compatible with the filtration system
Integrated Filter Purging
Our cartridge modules can incorporate an automatic compressed-air pulse-cleaning system.
The system periodically releases controlled air pulses through the filter cartridges to dislodge accumulated particles.
This can help:
- Maintain airflow
- Reduce filter pressure drop
- Extend filter service life
- Reduce manual cleaning
- Improve maintenance planning
How Do You Choose?
Consider:
Coating type + production volume + overspray loading + product size + airflow requirement + maintenance strategy + environmental requirements
There is no universal booth design suitable for every application.
We engineer the booth around the actual production process.
Convertible Spray Booths
For facilities with limited space, we can provide convertible booths with folding or retractable canvas walls.
The booth can be extended during spraying and folded away when not required.
This provides:
- Space savings
- Flexible working area
- Easier factory layout management
- Suitable for large products
- Practical solution for low-to-medium production
Accumulation Tank / Collection Floor
For applications where overspray or cleaning water needs to be contained, the booth can incorporate an integrated accumulation tank or collection system beneath the working area.
This helps prevent contamination of the factory floor and provides controlled collection for cleaning residues and process liquids.

Our spray booth solutions can include:
- Booth structure
- Exhaust fans
- Cartridge filtration
- Water curtain system
- Automatic filter purging
- Fresh-air intake
