4V/292 filter element for GAS TURBINE sector, fully burnable, without any toxic gas emission.
Filter medium: glass fiber, water repellency treatment and dual layer renforced structure standard and energy save (30%) versions.
Separators: automatic dispensing of thermoplastic wires (minipleat technique), which allow to optimize air flow, maintaning a constant pitch between pleats through their depth.
Frame: self-draining in MOPLEN (PPE), higher tensilen strength, lower density, higher termic resistance, higher abrasion resistance than polystyrene frames.
Sealing system: hard PUR automatically dispensed inside V elements and in side frame.
Outer protection grids: moulded HD polyethylene on all minipleat panels air outlet side (clean side).
Gasket: seamless type in semiexpanded PUR automatically dispensed.
