    To ensure the reliability of the tests, it is essential that the work carried out inside the cabinet does not become contaminated. To create an environment that is safe and particle-free, the vertical laminar flow cabinets we manufacture produce a stream of Class ISO 5 sterile air. This air passes through a H14 HEPA filter (manufactured pursuant to Standard EN-1822) at a constant speed, travelling downward through the cabinet in a vertical laminar flow and producing sterile air, protecting the product from external contamination and possible cross-contamination between samples.

    The cabinets that are equipped with our filtration system, which has a minimum efficiency rate of 99.995% for 0.3 µm particles in the upper part of the filter and an extraction rate of 100% as regards the air flow to the outside.

    Sample Protection. Total Sterility

    Cruma's vertical laminar flow cabinets guarantee a laminar stream of air with class ISO 5 air purity pursuant to Standard EN14644-1 thanks to our intelligent H14 HEPA filters, providing a minimum efficiency rate of 99.995% for 0.3 µm particles.

    These can be used in areas where it is difficult to extract contaminated air, such as the lower floors of buildings, and they can be placed in different locations, which it means that they can be easily relocated if needed.
    ico-cruma-ahorro
    Economic Savings and Easy to Set-Up
     
    No expensive works are necessary to install conduits to extract the gas to the outside which means there are no additional costs and no need to interrupt a laboratory working at full capacity.
    ico-cruma-ahorro-energetico
    Energy Savings
     
    Unlike other brands, our cabinets do not consume the air conditioning of the laboratory, which substantially reduces energy costs: the filtered air is not expelled to the outside, but recirculated back into the laboratory free of contaminating particles.

    Advantages

     

    Manufacture: the external surfaces are made of cold-rolled steel, coated with white epoxy, enamelled in ovens at 200ºC and resistant to the chemical compounds used for sterilization.

    Work Surface: the surface of the work chamber is made of white secured glass, highly resistant to impacts and chemical attacks.

    Absolute H14 HEPA Filter with a flow equalizer and an efficiency rate of over 99.995% for particles measuring 0.3 microns. Standards MIL-F51068C and BS 3298.

    Fan motors: double aspiration centrifugal fans, capable of providing a laminar flow in the work space, above all as regards dealing with filter saturation to a maximum value of 400 Pascal.

    Control Panel: Soft-touch keyboard with a switch for the LED lamps, UV ultraviolet lights, a maintenance system to control the airspeed through the HEPA filter that is electronically self-regulated and a control key to reduce speed in ECO mode.

    Lighting: LED lamps located in the centre with a prismatic diffusing screen to improve the distribution of light on the work surface.

    In the vertical laminar flow cabinets the stream of air passes through the H14 HEPA filter (manufactured pursuant to EN-1822) at a constant speed, travelling vertically through the cabinet in a laminar flow and producing a Class ISO 5 sterile environment (former American Federal Standard 209E) and protecting the product from external contamination and possible cross-contamination between samples.
