Using a sara LBS Sprint cleanroom door allows cleanroom operators to enter and exit their controlled environments quickly without risking contamination. The doors, which have been certified by the Fraunhofer Institute for cleanroom suitability, maintain a pressure difference up to 25Pa and offer contactless operation. With the fastest opening speeds on the market the doors also minimise exposure to external environments.
'An ISO Class 5 cleanroom has at most 100,000 particles that are larger or equal to 0.1µm per m3; the sara Sprint Cleanroom is able to consistently maintain this level of regulation in a normally functioning cleanroom,' says Ed Wilks, Operations Manager for sara LBS. 'It is the only door on the market today that is designed specifically for cleanroom use with an internationally recognised certification.'
In common with the rest of the Sprint range from sara, 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 are 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 that can deliver a wide range of speeds extremely smoothly as well as a wide range of options for connecting control safety devices.
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 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; however, 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 while vastly 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, and 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 1000/3500mm wide by 1000/3500mm high; specially designed, narrow side frames allow doors to be installed in confined areas.
'The sara Cleanroom Door is suitable for wide number of applications. There are a number of features as standard or optional that can ensure the door is perfect for your application,' adds Wilks. 'We have expert sales engineers available to provide advice on specific environmental requirements to ensure the correct specifications are met. This expert advice is available for all sara customers from the initial quote, through to after sale support services.'
