4.0 REVIEW OF USER REQUIREMENTS SPECIFICATION (URS):

DESCRIPTIONSPECIFICATIONS
EquipmentVertical Laminar Reverse Flow Powder Containment Station
SpecificationClass 100 Vertical Laminar Reverse Flow Powder Containment Station In S.S. 304(16G) construction, comprising as; standard features; MINIPLEAT HEPA filters 0.3µ; Prefilter 5µ; Intermediate filters (0.3µ 50% DOP HEPA); suitable motor blower assembly; MINIPLEAT HEPA filter for exhaust; plenum for prefilter and air circulation; SS filter protective grilles; white light; Stainless steel double walled side panels (PUF filled); Stainless steel in-built covings (all inside corners) to avoid dust accumulation; feather touch ON/OFF switches for blower & light; extra electrical points with switches; 3-off Magnehelic gauges indicate filter loading on supply and return sides; separate control panel box in S.S. 304(16G) Construction accommodating electrical fittings like; MCBs and on/off switches to avoid dust accumulation.
Overall Dimensions2050mmWx2260mmDx2535mmH
ProcessVertical Laminar Reverse Flow Powder Containment system is capable of maintaining a Class 100 work area meeting all requirements as per Cgmp
Material of constructionThe body of Equipment is of S.S. 304 construction.
HEPA filter [frame] construction Aluminium extrusion, food grade gasket on both sides.
Pre Filter [frame] construction: S.S.304
Motor Blower construction MS powder coated
Operation of Laminar Air Flow SystemSwitching of Laminar Air Flow by pressing the ‘ON’ switch. After getting the required differential pressure on the Magnehelic gauge, work can be carried out.
Brief Process DescriptionThese are Vertical Laminar Reverse Flow Cleanair Work Stations with HEPA-filtered air sweeping the area from top to bottom to protect the products from contamination as well as preventing the operators from inhaling potentially harmful active materials during sampling, weighing, and/or dispensing powders. The filtered air picks up aerosolized particles and forces them to travel in a predetermined flow pattern until trapped by the scavenging filters on the back panel of the unit. The airflow pattern is so maintained that the operators in the safe zone (approx 300 to 450mm into the open front of the cubicle) are not exposed to the dispersed particles. The return air passes through intermediate filters and enters the positive pressure plenum to be pushed downward through HEPA filters. 10% of the air is exhausted out of the zone through HEPA filters for maintaining a slight negative pressure inside to ensure that at no point in time, air movement can be outward.
CalibrationAll components that require calibration shall be identified and calibrated.
Calibration certificates are to be provided at the time of Installation qualification.
Qualifications/ DocumentationThe manufacturer shall complete and provide the documents about Design, Installation, and Operation Qualification, equipment validation, and detailed functional specifications.
Information of purchased/bought-out parts.
Circuit’s details.
Control systemThe equipment shall be controlled through an Electrical Switches system.
