Envair specialises in clean air and containment facilities for healthcare, research laboratories, biotechnology and the pharmaceutical industry, everywhere in fact where HEPA (High Efficiency Particulate Air) filter systems are used to provide a particle-free environment for critical work, or to contain contamination generated by the work within a defined area, or both.
All of our products are sold through a dedicated network of suitably experienced world-wide distributors and technical sales representatives covering the medical, clinical and laboratory sectors.
Our distributors are all exclusive within their region of coverage in order to ensure mutual commitment and a long-term focus on you, the customer.
Envair microbiological safety cabinets are widely used in pathology, microbiology and haematology laboratories to give protection against infection to technicians working with biopsy specimens, blood, sputum, etc.
Envair has specialised for many years in hospital pharmacy aseptic facilities where medicines are mixed and prepared for patients. Such medicines must be free of microbiological and particulate contamination. The work itself is carried out in Envair isolators (gloveboxes). These can be positive pressure, where the predominant requirement is for product protection, or negative pressure, where technicians require additional protection from potential contamination by cytotoxic drugs of unknown toxicity. Lead-lined isolators are used for handling radiopharmaceuticals in nuclear medicine. Envair is the world market leader in hospital pharmacy isolators and now works closely with specialists in hydrogen peroxide gassing systems to provide integrated solutions for high volume production facilities.
There are numerous applications in research that require clean air or containment or both. Envair’s unique ultra-safe double-filtered Class II microbiological safety cabinets, which are now available with by-pass exhaust systems, are to be found in cancer research laboratories around the world. Envair’s Class III microbiological safety cabinets are specified wherever research is being carried out into highly infectious diseases, including in military establishments engaged in chemical and biological defence. Research activities in many fields require air that is virtually free of particles. For these applications Envair has a range of horizontal and vertical unidirectional airflow cabinets and enclosures. Other research activities require controlled atmospheres, which may be low oxygen, or low relative humidity, or both. For these activities, Envair can provide specialised controlled atmosphere isolators (gloveboxes).
Envair can design and build specialised isolators in a variety of materials, including stainless steel and plastics, to enclose or link with bioreactors and other equipment used in biotechnology. Envair’s complete range of standard Class I, II and III microbiological safety cabinets, with larger versions to house robotic samplers, is also available for this market.
Envair has a wide range of application-based isolators for research, quality control and production, including controlled atmosphere isolators, negative pressure isolators, sterility test isolators and filling line isolators. In addition Envair has the capability to design bespoke units to the customer’s own URS (User Requirement Specification). Some activities can be carried out in open fronted unidirectional airflow cabinets and these can be linked into continuous production lines. Vertical unidirectional airflow enclosures are used to provide clean air over specific areas or equipment. Envair has a full understanding of GMP, validation and regulatory requirements in this industry.
Envair also provides solutions in primary production where powders are handled in large volumes. Downflow booths allow sampling and mixing of powders under controlled conditions. Bespoke isolators have been built for the safe offloading, charging, sub-dividing, pre-formulation and dispensing of APIs (Active Pharmaceutical Ingredients) from suppliers’ containers. Simple secure containment isolators have been developed and supplied for valves (such as split butterfly valves) for hoppers, vessels and reactors.
