PULSAIR® – Very high induction diffusion.

DIFFUSAIR® very high induction perforated metal ducts today offer the best alternative to classical diffusion installations.
Easy to implement, not needing adjustments and offering superior performance compared to classical air diffusers, they are today the most attractive product in terms of quality / price ratio.

CLASSICAL DIFFUSION

INSTALLATION TO AVOID

Requires 2 – 3 cladded collectors.
Awkward adjustment of air supply outlets.
Unreliable comfort quality.
Very high ducting lengths.
Take-up circuit advisable.
4 times longer to install!
Very high overall installation costs.

DIFFUSION is a more conventional blown-air technology that confers very good performance while ensuring user comfort.

DIFFUS’AIR® very high induction perforated metal ducts thus offer the best compromise in terms of installation quality / price ratio.

The basic principle remains the same: perforated metal ducts. But here the perforations are adapted to the classical DIFFUSION technique.

It is today most widely used in the perforated metal duct market. The dimensioning, lengths and positioning of DIFFUS’AIR® ducts are generally defined by the ordering customer, consultant or installation engineer.

Here too DIFFUS’AIR® can assist you in dimensioning.

Here too DIFFUS’AIR® can assist you in dimensioning.
Using our specific CFD (Computerised Fluid Dynamics) dedicated computer program, DIFFUSAIR® can offer you a quantitative estimation of your installation.
CFD has grown from a mathematical curiosity to become an essential tool for validating a DIFFUSION solution.
In the field of DIFFUSION type high-induction perforated ducts, this approach has become the focus or great research efforts as it allows to have access to all the instant data (speed, pressure, temperature) for each point in the field of calculation.

Product characteristics

The range of DIFFUS’AIR® perforated metal ducts or DIFFUSION Metal Ducts (GMD) covers diameters from 200 mm to 1,700 mm in 1.5 m length sections.
We market ducts delivered closed (ready for installation) or open in interlocking sections packaged on a pallet.
Each length section is terminated by a turned-out edge for assembly into one piece by sleeves.
Our perforated ducts are offered in all materials and all possible RAL colours.
They find application in all fields of activity (swimming pools, theatres, function rooms, retail outlets, airports, halls, industry, sports centres, hangars …).
