Peflex Insulated Flexible Duct 4"x25'


Peflex 4PG is an insulated Flexible Air connector consisting of two layers of pure aluminum and of two layers of a polyester binding a galvanized wire. 
Peflex 4PG is completely water and air tight, corrosion resistant and can withstand high static pressure. 
High static pressure resistance is achieve by having a tight distance between helix (1 inch) and by having the thicker wall in the industry (0.0041’’/0,105mm).

Peflex 4PG offer a high resistance to fire because of its unique quadruple laminating process leaving no flammable material exposed. 
All adhesive use in the quadruple laminating process contain fire retardant even if those material are not exposed.

Peflex 4PG has a much lower friction loss than regular cloth duct reducing the energy required by the system to move the air.

Peflex 4PG use John Manville Flexglass Formaldehyde free Insulation. 
John Manville Insulation is not an hazardous substance or mixture.
