Sara LBS has introduced the EN ISO 14644-1 Class 5-certified Sprint cleanroom door, designed to overcome the problem of industrial doors with no specific certifications for cleanroom environments.
An ISO Class 5 clean room has at most 10 (5) - 100,000 particles per m; Ed Wilks, operations manager for Sara LBS, said the Sprint cleanroom door is able to consistently maintain this level of regulation in a normally functioning cleanroom.
The cleanroom door is capable of high opening and closing speeds, maximum speeds of up to 2m/s are possible; 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's MCC Vector Control system, which can deliver a range of speeds very smoothly as well as a variety of options for connecting control safety devices.
The motor and barrel cover, door frame and bottom profile are all constructed from stainless steel, 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 variety of RAL colours is 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 50Pa.
The control panel is integrated into the side column; however, a non-contact operator panel is also available for fast, hygienic opening.
The option of including a non-contact safety beam further reduces the risk of touch contamination while reducing the risks to personnel and equipment as the beam recognises when an object is obstructing the door and prevents it from closing.
Sara is able to supply the cleanroom-certified doors with a number of options and variations to suit the customer.
The geared brake motor that drives the door can be fitted on either the right- or left-hand side, a battery backup is also available to ensure the door still works in the event of a power failure.
Door dimensions can be anywhere between 1,000/3,500mm wide by 1,000/3,500mm high; specially-designed narrow side frames allow doors to be installed in confined areas.
The Sara cleanroom door is said to be suitable for a variety of applications.
