Medical Claw Enclosed Systems

Powerex’s industry-first enclosed claw vacuum system decreases noise levels, allowing the vacuum system to be installed right at the point of use. Perfect when paired with their enclosed air systems, offering the lowest noise levels on the market. The claw pump design is extremely efficient and has very low maintenance cost; because there is no actual contact between the rotors and the cylinder wall, parts that need replacing or required maintenance is minimized.

The patented innovative sound enclosure reduces the vacuum pump sound intensity by 4-5 times which allows all Powerex WhisperVAC™ systems to safely fall in within the NIOSH 8-hour exposure limit.  The reduced sound levels also allows for greater flexibility in system placement since there is less nuisance risk for patients and hospital staff.

Vacuum System N/A The Powerex enclosed medical vacuum system is designed to create a suction to remove unwanted fluids or gases from hospital/laboratory working areas. The enclosed medical vacuum system package is compliant with the NFPA 99 requirements for Risk Category 1 systems.
Rotary Vane Vacuum Pump N/A Each pump shall be a rotary claw type vacuum pump, and shall bedirect-driven through a shaft coupling by a C-face, TEFC electric motor.

• Each vacuum pump shall be dry-running, featuring two clawtype, non-contacting rotors and shall not require any sealing fluid in the pumping chamber, assuring virtually maintenance-free operation.
• Each vacuum pump assembly shall include an integral relief valve.3
• Each pump within the system shall include a check valve, inlet and discharge flex connectors, a 5 micron inlet filter and a pump isolation valve on the intake connection.
Motor N/A The motor is continuous duty, C-face, TEFC, suitable for 208-230, or 460V, 3 phase, 60 hertz electrical operation.
Receiver N/A The internally lined ASME rated vacuum receiver shall be equipped with a sight gauge, isolation valves, and a manual drain.
Control Panel N/A The control system provides automatic lead/lag sequencing and automatic alternation of all pumps in order to equalize the amount of usage among the available vacuum pumps. The Premium NFPA Control panel shall include a gateway server card and all features listed below:

• PLC controller and a color touch screen panel which displays the operating status of the unit
• Building automation communication gateway with BacNet® protocol and Web server features. Web server features include email notifications in case the system is in alarm or has achieved one its maintenance intervals and requires service.
• Ethernet port for connection to BacNet® server or direct connection to facility Ethernet for viewing of system operations and status via device IP-address
• UL508A listed control panel in a NEMA 12 enclosure. The panel door will include: the HMI touch screen, an audible and visual alarms with an acknowledge button, and an HOA switch for each pump
• Magnetic contactors with Motor protector circuit breaks featuring through-the-door operators with lockable control knobs. Motor protector circuit breakers feature high inrush capability.
• Vacuum transducer for process control
• Single point power connection
• Redundant 120Vac control transformers with fused primary and secondary protection
• System overload trip, high temperature conditions or maintenance intervals for the pump will result in visual and audible alarms
Available Options N/A • Internal tank lining for corrosion resistance
• Variable Frequency Drive (VFD) Control Panel
Note N/A
  • 1 Air Flow shown at total system capacity.
