A chemical fume hood protects lab workers by venting solvent fumes and other harmful gases out of the laboratory and the indoor room air. Air flows into the cabinet beneath a movable sash at the front, and carries fumes up and out through the vent. Bypass fume hoods have an additional air intake above the sash which minimizes disruption of air flow in the work area due to movements in and out of the hood. Options in chemical fume cabinets now include energy efficient low flow fume hoods and hoods with an outdoor air intake (also known as auxiliary fume hoods) to avoid venting conditioned room air. Chemical fume hoods designed for specialized uses such as working with radioisotopes or perchloric acid are also available.

Topair’s Polypropylene Fume Cupboards are made of high-quality non-corrosive polypropylene with excellent chemical resistance. Polypropylene increases the product’s tensile strength and improves its thermal characteristics.
The Polypropylene Fume Cupboards protect laboratory staff from noxious fumes released by acids, dangerous gas and organic solutions – materials and acids which regular steel hoods may not withstand.
Harmful and unpleasant chemical fumes are removed from the controlled environment to facilitate a safe and pleasant work environment. The Fume Cupboard channels chemical vapors out of the building using an external fan installed on the roof or on an external wall.
The cupboards are designed for work with heavy chemicals, and have been independently tested to meet the requirements of EN-14175, ASHRAE 110-1995 standards....

- Polypropylene worktop – stainless steel optional.
- 5 mm front safety glass window with counterweight system
- Lower vented base cabinet made of polypropylene
- Air ventilation areas include perforations on the front and side area of the worktop and the grille at the rear.
Features: - 10.1” color touchscreen display
- VAV with air flow alarm and display
- Automatic laminar air velocity
- inflow is affected by the lab extracting system.
- automatic shutdown system for the down-flow when inflow system fails
- Clean bench functionality
- Cleanliness level – Class 100/ISO 5
- 800 lux LED lighting separated from the work area
