CG³
Over the past decades we have successfully equipped thousands of operating theaters and our customers have enjoyed the quality of our systems for many years. CG³, the third generation of laminar flow ceiling from Vokes Air, combines our proven experience in clean air ceilings with the latest technologies, unsurpassed quality and effective cost management.
CG³ meets todays increased requirements for performance, flexibility and quality, whilst minimising cost of ownership with a low energy consumption.
A special aluminium profile construction enables the the seamless integration of the CG³ system with media bridges, surgical lights and ceiling pendants, allowing the medical team to perform fluently with the surrounding equipment.
- Draft-free room climate
For maximum comfort - Minimal noise level
For an undisruptive environment - Smooth-surfaced housing design
Easy to clean and disinfect - Minimal pathogen concentration
< 10 KBE/m³ in the sterile field - Very low pressure drop
Highly economical energy consumption and operating costs - Seamless integration of ceiling mounted equipment and O.R. ceiling
To allow the medical team to work fluently with the surrounding equipment - Flexible, modular range of solutions
Adjustable to local requirements
Pressure Chamber
- Air sealed pressure chamber, made from stainless steel (1.4301)
- Smooth inner surfaces for simple disinfection during filter changes
- Pressure chamber mounted upon a stable profile, made from galvanized aluminium
- Air sealed housing for the integration of the O.T. light stand with openings for servicing
- Sealed ports for temperature pressure sensors
- Aerosol port
- Port for pressure differences measurement
- Separate seal leak test ports for each HEPA filter (in conjunction with test groove)
- Flange constructed from stainless steel (1.4301)
Filter and Diffuser Frame
Galvanised aluminium profile structure with integrated stainless steel frames for the placement of the filter cells and the CG-Diffuser. The aluminium profile provides rails for the easy and seamless placement of the false ceiling or other connecting equipment, and is also prepared for the integration of sterile field and O.R. illumination.
Filters
- HEPA filter cells, height 93 mm as H14
- Protected on both sides against accidental contact
- Filter change to the clean side
Sterile Air Diffuser-CG
- Transparent diffuser with double layer micro mesh, constructed from a special textile
- Assembly and disassembly without screws or tools
- Aluminium profile frame with an optimised air flow
- Pass through of the O.R. light stand
- Entire construction of the clean side smooth and without screws
Air Flow Stabilizers
- Glass curtains made from 8 mm shock resistant glass
- Secured in an aluminium frame to ensure the laminar air flow
- 200 mm in height
Frame for O.T. and Sterile Field Illumination
Integrated frame for the housing of the O.R. and sterile field illumination. The frame provides a seamless integration of the laminar flow ceiling and the lighting fixtures. Light bodies can be positioned directly in the frame.
Sterile Field and O.T. Illumination
- Clean room lighting for the illumination of the sterile field up to 2000 lux and for the surrounding operating theatre.
- Three tubes/lights with electronic dimming
- Prepared for a maximum of three circuits
