Permanent high system pressures over 0,5 bar require a pressure-resistant construction according to Pressure Equipment Directive (DRGL) in combination with the AD2000-instructions. However, pressure shock resistant fans could be constructed according to, e.g., VDI 2263. Manufacturing and calculations are carried out according to AD2000-instructions, too.
Furthermore, we supply shockproof fans (up to 2.5 bar shockproof), i.e. for vulcanization plants of submarine cables.
