NPD Sterile Garment Storage Cabinet
Model: NPD-235 | HEPA-Filtered Cleanroom Garment Storage
The NPD-235 is a self-contained clean-air storage system that helps protect cleanroom garments, wipes and other contamination-sensitive consumables from airborne particles. Continuous HEPA-filtered vertical downflow helps maintain a cleaner storage environment between laundering and use.
3 × 2 × 5 ft4 × 2 × 5 ft
Dimensions and construction can be customised to your cleanroom requirements.
Clean-Air Protection for Stored Garments
Cleanroom garments may accumulate airborne particles during storage. The NPD-235 draws ambient air through a washable pre-filter and uses a heavy-duty motor-blower assembly to deliver HEPA-filtered air vertically over the stored items. This helps limit particulate accumulation and supports cleanroom gowning procedures.
Designed for surgical garments, coveralls, hoods, boots, wipes and related consumables, the cabinet is suitable for pharmaceutical, biotechnology, healthcare, electronics and industrial cleanroom facilities.

How the Garment Storage Cabinet Works
Filtered downflow supports controlled storage of cleanroom garments.
Ambient Air Intake
Room air is drawn into the cabinet's air-treatment system.
Pre-Filtration
The washable EU-4/G4 pre-filter collects larger particles.
HEPA Filtration
Air passes through the EU-14 grade high-efficiency HEPA filter.
Vertical Clean-Air Downflow
Filtered air flows downward over garments to help reduce particle accumulation.
Reliable Cleanroom Garment Storage
The water-resistant, fire-retardant micro-fine glass-fibre HEPA medium is specified at better than 99.999% filtration efficiency at 0.3 µm. A washable EU-4/G4 pre-filter helps capture larger particles and extend the life of the main filter.
The cabinet can be fabricated from powder-coated CRC sheet or SS 304 stainless steel. Its self-standing configuration allows convenient positioning in cleanroom gowning rooms and other support areas. SS 304 construction is an option for facilities prioritising corrosion resistance and straightforward cleaning.
Applications
Designed for cleanroom garments and related contamination-sensitive consumables.
