This Pass box minimizes entry of contaminants and also cross contamination into the clean rooms.
Laminar Flow Benches are available in different sizes & configurations such as- Horizontal & Vertical flow pattern with standard / optional accessories.Working Space Dimensions in mm
24 HB/ VB
48 HB /VB
Laminar air as applied to clean room Technology is defined as air flow in which the entire mass of air within a confined space moves with uniform velocity along paralleled flow lines.
Laminar flow benches are specially designed for particulate and bacterial free sterile atmosphere to handle non hazardous non Pathogenic samples, cell & tissue cultures, alimentation controls in microbiology, Pharma product preparation. It assure a full product protection against contamination.
PREFILTER :Dry fabric air filter. Efficiency - 99.9 % down to 5 microns.

Contamination control plays an important role in Pharma industries (to maintain GMP), Operation theatres horticulture, tissue culture and bio fertilizer labs, Space Research, Semi Conductor & electronic Industries, Optics, Mineral Water & Food Processing industries, Mushroom Spon production etc.
Design of clean space or clean room encompasses much more than the traditional control of temperature, humidity & make up air to keep the environment acceptably "clean" other parameters that must be included in to the design of contamination control such as suspended particulates both viable and non viable, air flow velocity and air flow patterns, Cross contamination, noise, vibration & electro Static discharge within the clean cell.
For better contamination control a careful Selection of clean room products is essential. Purafil have adequate qualification, knowledge and experience of manufacturing Clean Air Products, conforming to ISOl 4644 -1 and 14664- 2 std.
The purafil dispensing / sampling /weighing booth allow to obtain delimited areas of clean and sterile air, through a unindirectional and descendant air filtered flow. Due to lower pressure in the working area, the possibility of cross contamination with other products is avoided . The main applications are dosing and weighing of raw material, sampling handling, hormones, cytostatics, etc. Either powders or liquids.
We offer following types of Curtains:
FLAT STRIP CURTAINS:
BUMPER STRIP CURTAINS
These curtains are ideally designed for heavy Industrial use where frequent movement of forklift & vehicles occur. Having vertical ribs along the entire length of the strip, these improve structural strength & reduce drag, abrasion, and wear and tear in industrial use.
COLD STORAGE STRIP CURTAINS:
Our Freezing quality PVC strips are an efficient way for saving energy and reducing heat loss in cold storage. These are also used in temperature control delivery vehicles. Available in sizes 200 mm W x 2 mm thk., these are manufactured using a special material with higher resistance to temperature differential upto 35 deg. C.
