Containment by Air Movement

With its open-fronted design, this type of system provides ease of access for both operator and material. It is ideal where a high degree of flexibility is desired.
 
Containment is achieved by air movement. Our Downflow booths and workstations are available in a variety of air-handling models.
 
When the Booth is operating under normal conditions air is pulled through the main working chamber to exhaust grills, normally situated in the rear of the Booths, suppressing air-borne dust away from the operators breathing zone.
 
Downflow Booths and Workstations provide a safe, controlled working environment and are called upon to carry out a wide range of operations.

BOOTH SUITE

The process requirement was to provide independently operated Downflow type Booths to carry out various small scale pharmaceutical operations within a controlled space.

A Suite of Downflow work Booths for the Pharmacy Lab, Comprising: -

These are self-contained walk -in type ventilated enclosures, purpose designed for the weighing of powder materials. The Booths incorporate an in-built multi-stage filtration and fan system operating on a recirculatory airflow arrangement.

The booth arrangements were designed to fit between the existing walls of a lab and are located against the rear facility wall.

WEIGH BOOTH

This self contained walk -in type ventilated enclosure, was purpose designed for the weighing of powder materials. The Booth incorporates an in-built multi-stage filtration and fan system operating on a recirculatory airflow arrangement.

The Downflow Booth is fitted with the following controls and instrumentation.

The Downflow Booth was designed to operate at a negative pressure to the surrounding environment providing class 100 (Laminar) airflow conditions within the working chamber.

LAF BOOTH

The station consists of a three-sided enclosure and a top. The operator works through the open front of the station.

This is one example of a number of stand-alone laminar airflow Stations purposely designed for use during the opening and manipulation of sparkler filter's.

The project called for multiple items of equipment to provide containment systems and solutions in several areas, within a pharmaceutical plant including: -

Each Sparkler station is a self-contained arrangement with the extracted air ducted away via the clients extract system. The airflow arrangement is a 'single pass' arrangement. The extract-air system pulls air from the room and horizontally across the area of operation. The air is extracted through perforations in the exhaust panels at the rear of the Station and into the clients exhaust duct.

An option for the extracted air to be HEPA filtered from the station and returned to the room environment is an option which could easily be integrated into this design .
