Horizontal Laminar Flow Cabinets

HZ-1 & HZ-2 & HZ-3 & HZ-4


Class ISO 5 horizontal laminar flow cabinets (former class 100) are ideal for jobs where it is necessary to ensure the products are protected from external contamination and cross-contamination. Thanks to the specific way the side walls, located inside the inner perimeter of the filter, are assembled it is possible to prevent any contaminants that may be present from entering the work area through the filter frame thanks to the Venturi effect. The air collected from the environment is prefiltered using polyurethane at high weight efficiency and, pushed by the fan engine to the retention plenum, it then passes through the absolute filter and is released into the work area. The air emerges from the H14 HEPA filter located in front of the operator, moving in a compact, laminar fashion creating a Class ISO 4, hence sterile, work space and making sure no contaminating particles are close to the product being handled.

Sample Protection. Total Sterility.

Our horizontal laminar flow cabinets guarantee a laminar stream of air with class ISO 4 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.

Economic Savings and Easy to Set-Up

No expensive works are necessary to install the cabinet which means there are no additional costs and no need to interrupt a laboratory working at full capacity.

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.


Yes, they all fit and are standard.

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.

    Sample Protection

    Clean area to handle and protect your samples.

    In our horizontal laminar flow cabinets the stream of air passes through the H14 HEPA filter (manufactured pursuant to EN-1822) at a constant speed, travelling horizontally through the cabinet in a laminar flow and producing a Class ISO 4 sterile environment (former American Federal Standard 209E) and protecting the product from external contamination and possible cross-contamination between samples.

    Single-stage filtration system with a minimum efficiency rate of 99.995% for particles of 0.3 µm in the upper part with an extraction rate of 100% as regards the air flow to the outside. Total protection for the sample.
