Air Shower

Faster Air Showers are used in clean facilities to remove dust from the outer surfaces of operators prior to entering a clean and dust free environment.

This thorough dust-removal is achieved by blowing filtered clean air at very high speed (exceeding 25 m/s) via special aluminium adjustable air-nozzles onto the operators in the main chamber of the air shower.

Key Features

Full body of the Air Shower manufactured in AISI 304L stainless steel with Scotch Brite pharmaceutical-grade finishing
Doors are manufactured in stratified safety glass of 8 mm thickness flush mounted within the body of the unit (without any unsightly aluminum frames), installed one in front of the other or square mounted; interlocked electromagnetic automatic release system allows the opening at the end of each dust removal cycle
Handle bars made in stainless steel
Ventilation is provided by double inlet centrifugal electrical fan with nominal air flow rate of 2.400 m3/h - at an operational pressure of 1.600 Pa
Filtration: 1st bank – Class H14 high pressure drop HEPA/ULPA filter according to CEN EN 1822, 2nd bank – Class G3 coarse particulate pre-filtration
Access for filters replacement is from the inspection panel mounted on top of the unit. Pre-filter panels are fitted with quick-release system (no screws needed for removal of the panel)
Pressure control is provided by means of analogic Dwyer manometer to check the differential pressure on the filter face
Air nozzle: The air is blown into the transfer chamber by means of adjustable air-nozzles made in aluminum with internal damper to regulate the air flow outlet. Air flow speed is manually adjustable within a range between 20 to 30 m/s
Half speed: Air flow speed reduction starts automatically at the end of each cycle

Airflow Principle

Air is pulled downwards and re-circulated via G3 pre-filter grids by the force of negative pressure within the transfer chamber in comparison to the surrounding environment.

The air is channeled through G3 pre-filters and high efficiency H14 HEPA/ULPA filter and blown into the chamber and onto the operator from various directions.

The resulting clean air inside the unit is in Class ISO 5 quality according to ISO 14644-1 Standard.

Cross Flow

Faster Cross Flow Units (CFU) have been designed for the pharmaceutical industry to control powder contamination and reduce operators exposure to powder. Powders are contained within the CFU preventing them from cross-contaminating other areas of the facility and products. Operators working within the CFU are protected from inhalation of potentially hazardous pharmaceuticals.

Although primarily used within the pharmaceutical industry, CFU’s can be found whenever there is a risk of dust contamination.

Pressure control provided by electronic output and analogic visualization by means of Dwyer manometers
Side containment provided by means of PVC strip curtains or stainless steel side walls

Airflow Principle

Air from the H14 HEPA filter passes down into the CFU chamber, through two pre-filters and back through the
H14 HEPA filter plenum. A small absolute filter mounted downstream of the fans generates a loss in the air recycling system, causing an inflow of air between the vinyl curtain and floor.

The vertical air stream carries away powders generated during manufacturing processes, passing through the pre-filter and being recycled or exhausted via H14 HEPA filters. This airflow pattern encourages a floor level air movement to prevent powder drifting through the room, and contamination of sterile products, which are generally kept at least 50
cm from the floor.

Horizontal LAF Trolley

Faster Horizontal Laminar Flow (LAF) transfer trolleys are used for the storage and the transfer of products that are sensitive to contamination, between two classified areas, generally separated by autoclaves.

The transfer trolleys are equipped with UPS (on-board battery) to maintain the laminar flow conditions within the LAF transfer trolley at all times. The battery level is monitored by a charge indicator.

Airflow Principle

Faster Mobile Laminar Flow Trolleys are self-powered unit by UPS battery. They provide a laminar air flow of Class ISO 5 (NF, EN, ISO 14644-1) air, blown horizontally from the plenum towards the loading door, sweeping through the main body, over shelves and draws on which the products are stored.

A constant positive pressure is maintained within the transfer trolley, greater than the pressure in the surrounding area – thereby eliminating the possibility of cross contamination.

Pass Boxes

Faster Ventilated Pass Boxes (also known as Transfer Hatches) allow users to transfer material between areas with differing grades of cleanliness. The materials may cross the Pass Box in both directions by different handling operations through two interlocked doors.

The basic unit can be fitted with germicidal lamps for sterilisation or decontamination cycles, to deliver the appropriate cleaning procedure according to the application to be performed.

Airflow Principle

Pass boxes can operate at both negative and positive pressure without compromising safety or cleanliness. The pressure pattern and operational airflow depends on the lay-out of the cleanroom or specific user requirements. They operate as standard in negative pressure in comparison to the pressure of the surrounding environment.

Positive step of pressure: the pressure inside the chamber is higher in comparison to the ‘dirty’ area and lower than the ‘clean’ area.

Overpressure: the pressure inside the chamber is higher in comparison to the ‘dirty’ and ‘clean’ areas.

Well of pressure: the pressure inside the chamber is lower in comparison the ‘dirty’ and ‘clean’ area.

Modular LAF Booth

Faster Vertical Laminar Flow Booths offer vertical laminar airflow of Class ISO 3 according to ISO 14644-1.

Units can be joined together to create small space up to room sized clean environments. These LAF modules can be supported by stainless steel legs or suspended from the ceiling.

Modules are assembled side by side or joined to create the dimensions required. Heavy duty PVC strips provide side containment and optimum efficiency of laminar airflow.

AISI 304L stainless steel construction, modular design in a wide range of sizes to provide large working areas with vertical or horizontal laminar airflow.

H14 HEPA filters meet ISO Class 5 in accordance with ISO 14644-1 and are protected by a washable polyurethane foam pre-filters.

Direct driven centrifugal fans are fitted with either electronic or autotransformer speed regulation, to compensate for progressive clogging of the HEPA/ULPA fìlter.
