SITC of Vacuum system

SITC of Duplex Medical Vacuum System

The duplex medical vacuum system should comply with HTM 02-01/NFPA 99/ DIN / EN / ISO-7396-1 standards. It should be Oil Sealed Rotary Vane/Oil Lubricated Screw Type to produces minimum 160 CFM (+/- 5%) as primary and 160 CFM as standby. The vacuum plant shall comprise air-cooled, oil lubricated rotary vane vacuum pumps suitable for both continuous and frequent start/stop operation at inlet vacuum levels between 500mmHg and 660 mmHg. The control system should normally employ automatic rotation of the lead pump to maximize pump life and ensure even wear.Vacuum pump inlets shall include a wire mesh filter and integral non-return valve to prevent oil suck back and pressure increases in the vacuum system. Each vacuum pump shall be fitted with anti-vibration pads between the pump foot and mounting frame. The plant shall be fitted with duplex bacteria filter system.

The vacuum receiver of 2000 liters shall be made of rust free corrosion resistant steel and fabricated as per BS/ISO for a vacuum pressure of 760mmHg. It should include bypass valves, manual drain valves, vacuum gauge.

SITC of Duplex Vacuum Bacterial Filters

The filters should be designed for removal of solid, liquid and bacterial contamination from the suction side of vacuum pump systems, preventing damage to the pump and the potential biological infection of the surrounding environment. The dryer should be particulate filter dryer with ability to remove particles as small as 1micron. Each individual filter shall have the capacity to deliver full design flow such that one set is designated duty and the other will be standby. Bacteria filters shall have efficiency at least 99.999% when tested by the sodium flame method in accordance with BS 3928:1969/as per required standard utilizing particles in the 0.02 to 2 micron size range. The pressure drop across each clean filter at 50% of the system design flow should not exceed 25 mm Hg (3 kPa) at a vacuum of 475mm of Hg (63 kPa). Bacteria filters shall be marked with the legend ‘Bio-Hazard’. Each bacteria filter shall be provided with a transparent sterilizable collection jar to collect condensate.

SITC of Wall Outlets Vacuum

Oxygen, air and vacuum outlets HTM or NFPA compliant should be quoted along with 2 probes for each out let. Both imported and indigenous outlets and probes should be quoted separately. The outlets and probes should be as specific and non- interchangeable. The gas outlets have heavy duty constituents and smooth connection and disconnection. The outlets must be labeled and color coded. Imported units should have UL Listing and Indian units must be IS/CE certified. Make Becon Medas, Dragger, Allied USA.
