W-Series 5000 RP Arrestors
99.81% Removal Efficiency. Six-Layer Expanded Paper.
The RTT W-Series 5000 High Efficiency RP Paint Arrestor is a single-layer exhaust filter designed for a wide range of spray booth and finishing applications. Six layers of expanded paper form an alternating labyrinth structure upstream of a light polyester backing – a construction that produces minimal initial air resistance while maintaining a high level of paint particle capture efficiency. Independent testing by LMS Technologies, Inc. confirmed an average removal efficiency of 99.81% and a paint holding capacity of 1,841 grams (4.1 lb.) under standard test conditions.
The W-Series 5000 performs best in applications where coatings produce a slightly tacky or wet overspray. The low initial pressure drop of 0.03 in. wg on a clean filter rises gradually to 0.13 in. wg at full load – a narrow pressure differential that keeps fan load and airflow consistent throughout the filter’s service life. The 5000 series is available in pad form (20″ × 20″ single layer, RP Part # W5000) and in roll form for continuous filter media applications.
Features
- Six-layer expanded paper construction forming an alternating labyrinth structure
- Light polyester backing upstream of paper layers
- Single pad per layer (number of pads in series: 1)
- RP Part #: W5000 (single layer, 20″ × 20″ pad)
- Available in pad form (20″ × 20″) and roll form
- Initial pressure drop (clean filter): 0.03 in. wg
- Final pressure drop (loaded filter): 0.13 in. wg
- Paint holding capacity: 1,841 grams = 4.1 lb.
- Average removal efficiency: 99.81%
- Construction designation: 6 Paper / 1 Light Poly
- Performs best with slightly tacky or wet overspray
- Tested by LMS Technologies, Inc.
Benefits
- Achieve high paint particle capture with minimal airflow restriction – 99.81% average removal efficiency at a clean filter pressure drop of only 0.03 in. wg keeps exhaust fan load low throughout the filter service cycle.
- Extend filter service intervals – a paint holding capacity of 1,841 grams (4.1 lb.) accommodates high paint loading before replacement is required.
- Maintain consistent airflow as the filter loads – the narrow pressure differential between clean (0.03 in. wg) and fully loaded (0.13 in. wg) limits fan performance variation throughout the service life of the filter.
- Fit a wide range of booth configurations – available in both pad and roll form to match standard exhaust filter banks and continuous roll filter systems.

Selection Guide
- Coating overspray is slightly tacky or wet
- Lowest possible initial air resistance is required
- Fan HP is limited and pressure drop must be minimized
- Overspray varies between wet, dry, and dusty across production runs
- A broader overspray compatibility is needed without changing filter type
- Slightly higher efficiency than the W-5000 is required
- Maximum capture efficiency is required (99.93%)
- High production volume demands longer filter service intervals
- Wet, dry, or dusty overspray is present at high feed rates
