Product Description

Fume Hoods:

GD is a pioneer in the field of Fume Hoods & Fume Extraction Systems. Constant innovation, stringent quality control and improvements in manufacturing processes ensure that Labexcel Fume Hoods are the best and undoubtedly the leader in the segment.

Besides being available in a wide range of models, Labexcel Hoods are designed to offer the complete solution to laboratory ventilation concerns. Integrated components including fume hoods, blowers, ducts, electrical services, plumbing options and base cabinets combine to provide a safe, efficient fume hood system for your laboratory.

Principal Features of Labexcel Fume Hoods


	Removable Back Baffle Easily accessible controls for service and electrical works
	Fully illuminated workspace
	Wide choice of sash arrangements
	Wide choice of chemically resistant linings
	Digital Face Velocity Meter with Alarm / Low Exhaust Indicator – optional feature to work with safe face velocity
	Efficient louver and bypasses
	Side panels can be opened for maintenance
	Aerodynamic design
	In-house fume hood performance testing facility as per ASHRAE 110-1995 guidelines
	Customized fume hoods offered for various applications like handling radioactive material, low maintenance, highly efficient, low noise, chemical resistant poly propylene blower

To make sure that the Fume Hoods we provide are the best among the available, especially in the context of your safety, they are tested under rigorous conditions.

Fume Hood Testing:

GD is the first Indian Laboratory Furniture Manufacturer to have established a state-of-the-art testing laboratory at the factory to evaluate the fume hoods performance as per ASHRAE- 110 (American Society of Heating, Refrigerating and Air - Conditioning Engineers) test as per the AM guidelines. It is a relative and quantitative determination of the efficiency of a fume hood to capture contaminants under a set of strict conditions.

The Test Laboratory is equipped with proper room pressurization system which generates air to be exhausted from the Fume Hoods being tested. The airflow is designed to provide turbulence free air entry at the front of the Hood. The test room has tight room envelope and precision electronic controls to maintain proper room pressurization.

All "Labexcel" Fume Hoods are type tested for their safety performance as per tests below:

Flow Visualisation Test

For low challenge, a small quantity of smoke is used for visual study of smoke flow pattern. For high challenge flow visualization, copious amounts of smoke is generated and released into the Fume Hoods.

Face Velocity Test

The sash is divided into grids and face velocity is measured at each grid point to analyze minimum, maximum and mean face velocity.

Gas Containment Test

This is a quantitative test where in a known quantity of gas is released within the Fume Hood and its leakage is measured at a stimulated breathing zone with an ultra precision Leak Meter and analysed.

Sash Movement Effect Test

The leakage of tracer gas is measured at rapid sash movement at the stimulated breathing zone.

VAV Response Test:

This is done when VAV controls are used for Fume Hood. The time required to regain the velocity at full designed velocity is measured.

We know that different laboratories have different needs, so we have built a wide range of Fume Hoods and other safety equipment to help you choose the right fit. And if you have a typical need, we will make one which is tailor
made for you.

Select from a range of Labexcel Fume Hoods Models like Bench Fume Hoods, Walk-In Fume Hoods, Low-Bench Fume Hoods, Special Purpose Fume Hoods, Customised Fume Hoods of assorted sizes from widths of 750 mm up to 2400 mm and with Liners like FRP, Polypropylene and with work surfaces ranging from Fibre Glass, Stainless Steel, Plastic Sheets, Epoxy Coated Steel, Ceramic Tiles, Granite and Imported Solid Epoxy Tops.
