Maxi-Safe Laminar Flow Booth
- On-site repairs are included in our service
- Prevents cross contamination in the work area
- Laminar air-flow bathes the internal work zone with clean air which has been filtered through Grade H14 HEPA filters
Applications
With more than 45 years of experience in air handling technologies, AES Environmental stand-alone Maxi-Safe Laminar Flow Booth are the optimal solution, when it is necessary to offer an economical solution to a wide range of processing application such as:
- Aseptic dispensing
- Assembly of electronics and optical components
- Cell culturing
- Media pouring
- Preparation of medical devices
- Sterility testing
Where the products, processes and at times the environment are sensitive to contamination.
Contaminants produced during media preparation are swept down and away from the operator as laminar air-flow bathes the internal work zone with clean air which has been filtered through Grade H14 HEPA filters. This process ensures that the stringent requirements of Class 5 (ISO) – necessary for the protection of products and operators during filling, transfer and packaging – are met.
Air at the work zone floor level is then mixed with ambient air from outside the booth which has been drawn in from under the protective solid wall or flexible PVC curtain, through a bank of prefilters located at the base of the rear work zone wall. The air is then recirculated with 30% being exhausted to ambient at ceiling height via a second HEPA filter. This procedure ensures that negative pressure within the working space is maintained, thus guaranteeing that there will be no breach of the containment boundary.
Construction
AES Environmental Maxi-Safe Laminar Flow Booth are constructed in powder coated mild steel, 304 or 316 stainless steel or a combination of both. With a variety of standard dimensions (height, width and safe working depths) our booths can also be custom engineered to any size.
Fans
Variable speed direct drive centrifugal fan/blowers enable separate airflow adjustment throughout the filter life and allow adjustment of the supply air velocity.
Climate Control
In dealing with applications involving powder materials, optimum temperatures and relative humidity need to be maintained. It must be borne in mind that both a filling machine motor and the unit’s fans will generate a considerable amount of heat. As an option cooling can be achieved by the fitting of an air-conditioning system.
Control Panel
A modern, proven control panel provides one touch access to all functions including servicing. A fully integrated self diagnostic processor with digital status display up by an audible and visual alarm guarantees your safety.
Quality Assurance
Every booth is factory tested and certified by a NATA registered laboratory to establish compliance with performance requirements of AS1386, Part 5.

Laminar Flow Booth Testing for UK Laboratories and Cleanrooms
Regular testing of Laminar Flow Booths (LFBs) is essential to ensure a controlled, particle-free environment for sensitive laboratory and manufacturing processes. Our on-site certification service verifies that your booth is operating effectively, providing reliable product protection and contamination control. Each visit includes a visual inspection, airflow velocity profiling to confirm uniform laminar flow across the working zone, and HEPA filter integrity testing using an aerosol challenge method to check for leakage. We also perform smoke visualisation tests to demonstrate airflow patterns and confirm containment of airborne particles within the booth. Supporting assessments of noise, vibration, and lighting levels help ensure safe and comfortable day-to-day use. Following testing, a detailed compliance report is issued in line with UK health and safety guidance, giving your organisation documented assurance of performance and regulatory compliance.
Mechanical Inspection
This includes the motor/ blower unit, vibration mountings, switch functions, gaskets, pre-filters and HEPA filters.
Check for System Integrity
Challenge for filter leakage to AS 1807.6 and AS 1807.7
Ensure the work area is not violated by room air
Test for induced air leakage in the work zone.
Prevent cross contamination in the work area
Check and adjust air velocity and uniformity of airflows.
Establish HEPA filter life and performance
Measure static pressure of filters and electronic motor current.
Check environment factors
Measure light output, sound level and germicidal ultraviolet lamp efficiency.
