Arrow Instruments Calibration

We provide and extensive range of services pertaining to clean room validation by our panel of expert professionals available with us.Cleanroom Validation/HVAC Validation is performed for a variety of reasons. To ensure that the design of the facility is fit for its intended purpose; to ensure that the facility, equipment, and environment meets User Requirement Specifications (URS); to ensure that the facility, equipment, and environment meet defined regulatory requirements; to ensure that the facility, equipment, and its environment function together as a system to meet defined standards.

HEPA filter is a High Efficiency Particulate Air filter.HEPA is an acronym that stands whether for an air purifier or other implementation,many benefits and claims.
The Institute of Environmental Sciences and Technology dictates that a HEPA filter must trap 99.97% of particulates 0.3 microns or larger. This does not mean that the filter cannot trap particles smaller than 0.3 microns, because many HEPA filters can; it is simply the threshold that must be reached in order to carry the HEPA name.
What is a micron?Particles range from ultra-microscopic to entirely detectable to the human eye. Microns, which are one-millionth of a meter, are how particles are measured. To give you a better idea of the size of a micron, or less than a micron, consider that we cannot visually see anything less than 10 microns. Bacteria can be anywhere from 0.3 to 60 microns, and 1 inch equals 25,400 microns.

Depending on the size of the particle, this can happen in four different ways: Inertial Impaction, Diffusion, Interception, or Sieving.

Aerosol particle counters determine the air quality by counting and sizing the particles in the air. They are mainly used in cleanroom applications. Since cleanrooms have defined particle count limits, aerosol particle counters are used to test and classify the cleanroom to ensure it is up to standard
