DETAIL:
Product Overview
The Cargo Air Shower Room is a heavy-duty contamination control unit designed specifically for cleaning pallets, cartons, drums, equipment, and raw materials before they enter a cleanroom or controlled environment. It directs high-velocity HEPA-filtered air through adjustable nozzles to remove dust, particles, and fibers from external surfaces of incoming goods.
This unit is essential for facilities where material transfer poses a contamination risk, ensuring that only clean items pass into the production area.
Key Features
-
Large Internal Clearance
Oversized dimensions accommodate standard pallets (800×1200 mm), drums, trolleys, and even small forklifts. -
High-Efficiency Filtration
Equipped with HEPA or ULPA filters (≥99.99% efficiency at 0.3 µm or 0.1 µm) to deliver particle-free air jets. -
Interlocked Doors
Heavy-duty magnetic or electronic interlocks prevent both entry and exit doors from opening simultaneously, maintaining cleanroom pressure and preventing cross-contamination. -
Multi-Directional Air Nozzles
Strategically placed stainless steel or ABS nozzles on side walls, ceiling, and optionally the floor to ensure complete surface coverage (360° cleaning). -
PLC Control System with HMI
Industrial-grade controller with adjustable cycle time (15–300 seconds), emergency stop, automatic cycle start, cycle counter, and audible completion alarm. -
Rugged Industrial Construction
Manufactured from 304 stainless steel (or 316L for corrosive environments) with seamless welding and rounded corners for easy cleaning. -
Energy-Saving Operation
Low-noise blower with standby mode and timer-controlled shutdown reduces power consumption between cycles.

1
How often should air shower filters be maintained?
Check air velocity regularly using anemometer (must remain ≥20 m/s). Replace pre-filters and HEPA filters based on differential pressure gauge readings or scheduled maintenance plan. Clean interior walls monthly with lint-free cloth
2
Can multiple people use an air shower simultaneously?
Strictly adhere to maximum occupancy (usually 1-2 people). Crowding disrupts indoor airflow and leads to incomplete purification. Allow intervals between groups for self-purification
3
What personal preparation is required before entering?
Change into dedicated lint-free cleanroom clothing, ensure hair is completely covered by cap, remove all jewelry, avoid makeup and perfume that shed particles. Street clothes are significant contamination sources.
4
Why is rotating during the shower cycle important?
Standing still creates purification "dead spots" where airflow cannot reach areas like back, underarms, and knees. Active rotation (at least one full turn) with arm movements ensures complete surface exposure.
5
What happens if both doors are opened simultaneously?
Opening both doors bypasses the airlock function, allowing unfiltered non-clean air to flow directly into the clean area, completely destroying pressure differential and compromising cleanliness classification
6
What is the proper procedure for using an air shower?
Enter, close outer door completely, stand in center, slowly rotate 360 degrees with arms raised for thorough coverage, wait for preset time (15-30 seconds), then open inner door and enter clean area
7
Where should air showers be installed in a cleanroom?
Install between changing rooms and clean areas, or between ISO 8/ISO 7 classified areas and unclean areas. Personnel pass through after changing into cleanroom clothing but before entering the controlled environment.
