Filter elements.
MultiPlus.
DELBAG® MultiPlus filter elements have been proven in gas turbines, compressors and engine plants worldwide, even under the most difficult conditions. The robust method of construction provides a long service life, excellent energy efficiency, high air purification and a maximum operational reliability.
MultiPlus filter elements are based on modern, moisture repellent impregnated micro fiber fleece. High precision manufacturing technology enables an optimum utilization of the entire filter area. The robust ABS frame is break proof up to the low temperature range. On pure air side, solid aluminum grilles protect the filter even under extreme overload. Protection grille and filter media leaks are prevented, because of the fixed grouting of the frames.
