Hoods and fume hoods

Hoods

A laboratory hood allows the extraction of vapors due to the use of other devices. The vapors extracted from a laboratory hood are either filtered or discharged to the outside.

Self-supporting hood:

Self-supporting hoods consist of:

  • 2 sides in white waterproof melamine 19 mm thick resting on the bench.
  • 1 interior ceiling, 1 front in 19 mm thick white water-repellent melamine.
  • 1 Ø 200 tap on the interior ceiling
  • Possibility to include lighting.

Hanging hood:

Hanging hoods consist of:

  • A mechanically welded frame in tube section 30 × 30.
  • 2 sides, 1 interior ceiling, 1 front in 19 mm thick CTBH white waterproof melamine.
  • 1 Ø200 tap on the interior ceiling.
  • Possibility to include lighting.

The hoods are suspended under the ceiling by lines which are adjustable in height and fixed to the wall.

Fume Hoods

Risk prevention in chemical laboratories is a concern which has seen considerable development in recent decades. In this area, the increase in the use of fume hoods and the progress made in their design have brought a lot.
However, fume hoods are pieces of equipment that require heavy infrastructure and generate high operating costs.

Laboratory fume hood placed on bench:

Complies with standards EN 14175 and XPX 15.206
