Rotary Claw Vacuum System
The Ohio Medical Oil-Less Rotary Claw Medical Vacuum System is fully NFPA 99 compliant for use in medical vacuum and WAGD applications. The unit consists of electric motor driven pumps, vacuum receiver, electrical control system, and interconnection piping and wiring. The components are modularly assembled to accommodate most existing doorways and designed for serviceability. The packaged unit is factory tested prior to shipment and warranted for a period of 30 months from date of shipment or 24 months from date of start-up.Vacuum Pump Module
The Rotary Claw Vacuum Pumps are single stage, and air cooled. The pump design utilizes two ductile iron claw type rotors rotating in opposite direction inside a cast iron housing. The timing of the rotors are maintained by a precision gear set which is separated from the oil free pumping chamber by a combination of lip seals. The vacuum pump assembly also includes a 5 micron particulate inlet vacuum filter, vacuum regulator/relief valve, and exhaust silencer. The assembly also includes high temperature switch, check valves, pump isolation valves, a source isolation valve and flexible connectors.
The Vacuum Receiver is constructed to ASME standards, rated for full vacuum, and include a valved by-pass, manual drain valve, vacuum gauge and the National Board label.
The UL listed electrical motor control system contains a fuseless design in a NEMA 12 enclosure. The “Continuous On Demand” feature stops the operation of the motors during periods of low or no demand. The controls include individual self protected combination motor controls with short circuit, single phase and thermal overload protection, Soft Start Technology, individual 120 volt control circuit transformers with fuseless primary and secondary protection, pressure sensors, and an electronic controller to automatically switch the operating sequence of the vacuum pumps. The cabinet door has an HMI (Human Machine Interface) Color Touch Screen system status display to include system pressure, pump operation, accumulated time, maintenance interval, fault conditions, and silence button; lighted Hand-Off-Automatic selector switches and safety disconnect operating handles.
All required local alarm functions are integrated into the packaged system. The circuitry is designed so the audible signal can be silenced and the visual indicator will remain until the fault has been cleared and the reset button actuated. Local alarm functions are provided for reserve pump in use (lag alarm). Dry contacts are furnished for remote (master) alarm signals.
Included for job site installation are inlet and discharge flexible connectors, source isolation valve, vibration mounting pads, and touch-up paint.
