Sprint for the cleanroom
Sara LBS launches ISO certified cleanroom door
In common with the rest of the Sprint range from UK-based sara/LBS, the Cleanroom Door is capable of high opening and closing speeds, where maximum speeds of up to 2m/s are possible. The company says this ensures that air exchange and particle emission is kept to a minimum when doors are in operation. The high speed is made possible by the inclusion of sara/LBS’s MCC Vector Control system that delivers a range of speeds extremely smoothly, and options for connecting control safety devices.
Ed Wilks, operations manager for sara/LBS, said: “An ISO Class 5 cleanroom has at most 10 (5) = 100,000 particles per m³; the sara Sprint Cleanroom is able consistently to maintain this level of regulation in a normally functioning cleanroom. It is the only door on the market today that is designed specifically for cleanroom use with an internationally recognised certification.”
The Cleanroom Door’s motor and barrel cover, door frame and bottom profile are stainless steel and the smooth surface is easy to clean and avoids the accumulation of particle deposits. The curtain uses PVC with fabric reinforcement strips; the strips are red or blue as standard but a wide variety of RAL colours are available as an option.
To ensure that high air ingress protection is achieved, gaps between the curtain and side columns are kept to a minimum and all components are well sealed, including the cable guide. The door is suitable for use with rooms with a pressure difference of up to 50 Pa.
The control panel is integrated into the side column but a non-contact operator panel is also available for fast, hygienic opening. The option of including a patented non-contact safety beam further reduces the risk of touch contamination and risks to personnel and equipment as the beam recognises when an object is obstructing the door and prevents it from closing.
Sara/LBS can supply the doors with a number of options and variations. The geared brake motor that drives the door can be fitted on either the right- or left-hand side, and a battery backup is available to ensure the door still works in the event of a power failure.
Door dimensions can be between 1000/3500mm wide by 1000/3500mm high. Specially designed, narrow side frames allow doors to be installed in confined areas.
