Air Purification Equipment
Air shower for cleanrooms
Product Overview
Global Hi-Technologies’ Go-Clean Air Purification Equipment range provides essential entry systems for cleanrooms, designed to minimise contamination from personnel and materials. Installed between clean and non-clean areas, these systems use high-velocity clean air to remove dust before entry. Electronically interlocked doors act as an airlock, preventing outside polluted air from entering the clean environment. Each system is engineered for controlled entry, combining G4 pre-filter and H13 HEPA filter with 2-stage filtration, 360-degree adjustable stainless steel nozzles, fully automatic infrared induction blowing, and LCD time display with adjustable shower time (0–99 seconds). The air velocity of the nozzle reaches 22–27 m/s with low noise centrifugal fan operation.

Key Features & Benefits
2-Stage HEPA Filtration
All Go-Clean air showers employ a dual-stage filtration system: a G4 pre-filter captures large particulates before a H13 HEPA filter removes particles down to 0.3 μm with 99.95% efficiency. This two-stage approach protects HEPA filter life while ensuring that only particle-free air reaches personnel or cargo during the decontamination cycle.
High-Velocity 360° Adjustable Nozzles
Stainless steel nozzles are adjustable through 360 degrees, enabling full-body coverage regardless of personnel orientation. Air velocity from each nozzle reaches 22–27 m/s, sufficient to dislodge surface contamination from clothing and exposed skin. Low-noise centrifugal fan technology keeps operation below 65 dB(A), minimising noise impact in adjacent cleanroom areas.
Automatic Infrared Induction & Interlocked Doors
Fully automatic infrared induction triggers the blowing cycle on personnel entry, eliminating the need for manual activation. Electronically interlocked doors prevent entry and exit doors from opening simultaneously, maintaining the air pressure differential that keeps contaminated outside air from entering the clean environment. The LCD panel displays the shower countdown and allows timer adjustment from 0 to 99 seconds.
Customisable to Facility Requirements
Global Hi-Technologies customises all air shower configurations to match facility layout, traffic volume, cleanliness class requirements, and operational workflow. Door types, blowing direction, chamber dimensions, material finish, and power supply specifications are all configurable. Personnel and cargo variants are available with a full selection of door systems including automatic rolling, swing, sliding, and PVC fast-shutter options.
H13 HEPA Filtration — 99.95% Efficiency
The G4 pre-filter and H13 HEPA filter combination provides a two-barrier filtration approach that achieves 99.95% removal efficiency at 0.3 μm particle size — the most penetrating particle size for HEPA filters. The pre-filter extends HEPA filter service life by capturing coarse particulates before they reach the primary filter media, reducing maintenance frequency and operating cost in high-traffic cleanroom entries.
Airlock Architecture — Contamination Prevention
Electronically interlocked doors form an airlock between the clean and non-clean zones. The interlock prevents both entry and exit doors from opening simultaneously, maintaining the pressure differential that stops outside polluted air from entering the cleanroom. This is a fundamental requirement for cleanroom entry systems operating at ISO Class 5 through Class 8 and equivalent standards.
Professional Deployment & Ongoing Support
GHT provides end-to-end project delivery — from site survey and system configuration through to installation, commissioning, and operator training. Post-deployment, clients receive comprehensive aftersales technical support including on-site maintenance and service assistance. All models carry a 12-month standard warranty, with extended warranty packages available for long-term facility requirements.
How it works
1
Personnel or Cargo Approaches the Air Shower
Personnel or a goods trolley enters the air shower chamber through the entry door. The infrared induction sensor detects presence automatically, triggering the decontamination cycle without any manual intervention required.
2
Interlocked Doors Secure the Chamber
The electronically interlocked door system prevents both entry and exit doors from opening simultaneously. This airlock prevents outside polluted air from entering the cleanroom and maintains the pressure boundary between the clean and non-clean zones throughout the decontamination cycle.
3
High-Velocity Clean Air Jet Initiated
The centrifugal fan draws ambient air through the G4 pre-filter and H13 HEPA filter, producing a clean, high-velocity airstream. The 360-degree adjustable stainless steel nozzles direct this stream at 22–27 m/s across all surfaces of the personnel or cargo to dislodge dust, particulates, and contaminants.
4
Shower Timer Counts Down on LCD Display
The LCD panel displays the remaining shower time throughout the cycle. Shower duration is adjustable from 0 to 99 seconds via the control panel, enabling facilities to calibrate decontamination time to their cleanliness class requirements and traffic throughput needs.
5
Dislodged Particles Removed by Exhaust
Contaminated air carrying dislodged particles is exhausted from the chamber before it can settle on personnel or cargo. The continuous clean-air injection and exhaust cycle ensures that removed contamination does not re-deposit during the shower duration.
6
Cleanroom Entry Authorised
On cycle completion, the exit door releases and personnel or cargo may proceed into the cleanroom. The entry door remains interlocked until the exit door has closed, maintaining the airlock integrity for the next user cycle.
Cleanroom compatibility: Go-Clean air showers are designed for integration between ISO Class 5–8 cleanrooms and adjacent non-clean areas. Configuration, shower time, and door type selections are guided by the facility’s cleanliness class requirements and traffic volume specifications.
Compatible with Facility Management Systems
Go-Clean air showers are compatible with building management systems, access control platforms, and facility monitoring software. Integration with existing infrastructure allows centralised control, entry event logging, and real-time status monitoring across multiple air shower units within a single facility or campus.
Warranty
All Go-Clean air shower models include a 12-month standard warranty covering manufacturing defects across all components — chamber, filtration system, fan units, nozzles, interlocked door mechanisms, and control panel. Extended warranty packages are available on request for facilities requiring longer coverage periods.

Frequently Asked Questions
What door types are available for personnel air showers?
Personnel air showers support manual doors, automatic 90-degree doors, sliding doors, high-speed roll-up doors, PVC curtains, and open-entry configurations. The choice depends on traffic volume, personnel flow direction, and the cleanroom class requirements of the facility. Global Hi-Technologies recommends the appropriate door type based on a site consultation.
Can air showers be customised to facility requirements?
Yes. Global Hi-Technologies customises air showers as per customer requirements, including chamber dimensions, material finish, door types, blowing configurations (single-side, top-down, double-side, triple-side), and power supply specifications. Customisation is available across both personnel and cargo air shower variants.
What filtration standard do the air showers use?
All Go-Clean models use G4 pre-filter and H13 HEPA filter with 2-stage filtration, achieving 99.95% efficiency at 0.3 μm particle size. The G4 pre-filter captures larger particles first, extending HEPA filter life and reducing maintenance frequency. This filtration standard is appropriate for ISO Class 5 through Class 8 cleanroom entry applications.
How loud are the air showers during operation?
All models operate at less than 65 dB(A), using low-noise centrifugal fan technology. This level is comparable to normal office conversation, minimising noise impact in adjacent cleanroom corridors and work areas during the decontamination cycle.
What is the shower duration and can it be adjusted?
The shower duration is adjustable from 0 to 99 seconds via the LCD control panel. Facilities calibrate shower time to their cleanliness class requirements and personnel traffic throughput needs. Typical settings range from 15 to 30 seconds for standard pharmaceutical and electronics cleanroom applications.
How does the door interlock work?
The electronically interlocked door system prevents the entry and exit doors from opening simultaneously. When a person enters through the entry door, it locks until the shower cycle completes and the person exits through the exit door. The entry door then unlocks for the next person. This airlock principle maintains the pressure boundary between the clean and non-clean zones, preventing contaminated outside air from bypassing the decontamination chamber.
What is the difference between personnel and cargo air showers?
Personnel air showers are configured for people entering the cleanroom — with chamber dimensions, nozzle height, and door configurations suited for single or small groups of personnel. Cargo air showers are designed for the decontamination of materials, goods, trolleys, and pallets entering the cleanroom, featuring large-format door systems such as automatic rolling up doors, double swing doors, and PVC fast-shutter doors to accommodate bulk material flow. Both variants use the same H13 HEPA filtration standard.
What warranty is provided?
All Go-Clean models include a 12-month standard warranty covering manufacturing defects across all components — including the filtration system, fan units, nozzles, interlocked door mechanisms, and control panel. Extended warranty packages are available on request for facilities requiring longer coverage periods.
