Paint Booth Filters by Autocoat Engineering

Filters are the most critical consumable component in any paint booth or spray booth. They protect the fan motor from paint-laden air, maintain correct airflow velocity across the spray zone, and ensure overspray particles are captured before reaching the atmosphere. Autocoat Engineering supplies high-quality inlet, exhaust and water wash filters compatible with all booth types — including our own and those from other manufacturers.

Types of Paint Booth Filters

Inlet Filters

Installed at the air supply plenum, inlet filters remove dust and particulates from incoming air before it enters the painting zone. Essential for achieving a dust-free finish.

Exhaust Filters

Positioned in the exhaust plenum, these filters capture paint overspray particles before air is discharged. They protect fans, ductwork and the environment from contamination.

Water Wash Filters

Used in water wash spray booths, these filtration stages use a water curtain to scrub overspray from exhaust air. Ideal for high-volume operations requiring continuous operation.

Why Regular Filter Maintenance Matters

Blocked or saturated filters are the most common cause of poor paint finish quality in industrial spray operations. When exhaust filters become loaded with paint, back pressure increases, air velocity across the spray zone drops and solvent vapour lingers — leading to runs, dry spray and uneven film build. Inlet filter neglect allows dust and fibres into the booth, causing inclusions in the cured film.

As a general guideline, exhaust filters should be inspected every 50–80 operating hours and replaced before pressure drop across the filter exceeds the manufacturer's specification. Inlet filters typically require replacement every 200–400 hours depending on ambient conditions. Autocoat Engineering recommends scheduling filter changes as part of a planned preventive maintenance programme rather than waiting for visible signs of failure.

We supply replacement filters for all our booth models and can also source filters for third-party booths. Contact us with your booth model and filter dimensions for a prompt quotation.

FAQ

Frequently Asked Questions

What types of paint booth filters does Autocoat sell?

Autocoat sells ceiling diffusion filters (intake), exhaust paper paint-arrestor filters, glass-fibre cardboard filters, multi-layer overspray pads, EU3-EU13 fine air filters, HEPA filters for clean-room booths, water-wash media and pre-filters. Custom sizes available for any booth brand. We stock standard sizes for next-day dispatch.

How do I choose the right paint booth filter?

Select filters by three criteria: airflow capacity (m³/h matching your booth blower), filtration grade (EU3 for primer, EU5+ for topcoat, HEPA for premium finish), and frame size matching your existing rails. Send your booth model or photos to Autocoat and we recommend the correct filter set in 24 hours.

What is the difference between intake and exhaust filters?

Intake filters sit at the ceiling and clean incoming air to keep dust off the wet paint surface — typically EU5 to EU13 grade. Exhaust filters catch overspray on the way out, protecting the blower and stack — typically pleated paper or fibreglass pads. Both must be replaced together for balanced airflow.

Are Autocoat filters compatible with imported booths?

Yes. Autocoat manufactures filter cartridges and pads to fit imported Chinese, European and American paint booths — common brands include Saima, Ferrara, Garmat, GFS and Spanesi. Just share the filter dimensions, frame depth and EU rating, and we supply matching replacements at competitive pricing. Send enquiry for exact filter cost.

How long do paint booth ceiling filters last?

Ceiling diffusion filters last 6-12 months in single-shift operation with normal paint volumes. Heavy three-shift use or solvent-rich automotive applications may shorten life to 3-4 months. Visual inspection — uniform colour and no clogging — combined with pressure-drop checks gives the most reliable replacement signal.

What is an EU-class filter rating?

EU classes (EU1 to EU13) are the European standard for air filtration efficiency — higher numbers mean finer filtration. EU3 captures coarse dust, EU5 catches fine particulate, EU7-EU9 are used for premium automotive paint booths, and EU13 (HEPA) is used for clean-room and aerospace finishes.

Do you supply paint booth filters in custom sizes?

Yes. Autocoat manufactures non-standard ceiling and exhaust filters cut to any width, length and depth. Minimum order is typically 10 pieces. Lead time for custom sizes is 5-7 working days. Send a sample, sketch or dimension sheet — our team confirms specs and price within 24 hours.

How are paint booth filters shipped in India?

Autocoat ships filters across India via DTDC, Delhivery and Safexpress. Standard sizes leave Thane within 24 hours of payment. Bulk orders ship by surface transport in wooden crates. Delivery times: Mumbai-Pune next day, Maharashtra 2 days, North/South India 3-5 days, North-East 5-7 days.

Are paint booth filters washable or single-use?

Most paint-arrestor and ceiling filters are single-use because trapped paint and solvent permanently saturate the media. HEPA pre-filters and metal mesh filters can be vacuumed and reused 2-3 times. Water-wash booth media is typically permanent — only the chemical bath needs replacement. Autocoat advises filter type during specification.

What is the price of a paint booth filter set in India?

The cost of a paint booth filter set varies depending on size, type, and grade. Key factors include filter dimensions, frame depth, EU class (EU3 to EU13/HEPA), media type (paper, fibreglass, washable) and order quantity. Bulk orders attract trade discounts.
