Original filters, separators, oil and maintenance kits help maintain operational reliability and performance.\u003c\/p\u003e\n\u003cdiv style=\"background:#f5f5f7;border-radius:10px;padding:14px 16px;margin:18px 0;\"\u003e\n\u003cstrong\u003e📌 Important:\u003c\/strong\u003e The compressor is offered without an air receiver, dryer or external compressed air filters. The complete compressed air station must be designed to suit consumption, the required air quality and the operating conditions.\u003c\/div\u003e\n\u003chr style=\"border:0;border-top:1px solid #ddd;margin:30px 0;\"\u003e\n\u003ch5 style=\"font-size:18px;margin:0 0 12px;\"\u003eTypical applications\u003c\/h5\u003e\n\u003cp\u003eThe Comprag DV90 is particularly suitable for industrial and commercial compressed air networks with fluctuating consumption—for example in production, metalworking, CNC manufacturing, assembly, painting, blasting technology, packaging, workshops and automated systems. With a constant base-load demand, it can also be combined with other compressors to form an energy-optimized station.\u003c\/p\u003e\n\u003chr style=\"border:0;border-top:1px solid #ddd;margin:30px 0;\"\u003e\n\u003ch5 style=\"font-size:18px;margin:0 0 12px;\"\u003eFrequently asked questions\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhy is the DV series variable-speed controlled?\u003c\/strong\u003e\u003cbr\u003eSo that the delivered volume automatically follows the current compressed air consumption. This reduces idle times, keeps the line pressure stable and can significantly lower energy costs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does 1:1 direct drive mean?\u003c\/strong\u003e\u003cbr\u003eThe electric motor transmits its power directly to the screw block via a flexible coupling. There is no belt drive and no additional transmission stage.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan the DV90 be integrated into a control room?\u003c\/strong\u003e\u003cbr\u003eYes. The v-Log controller supports MODBUS RTU and also enables group control of multiple compatible compressors.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs a refrigerated dryer included?\u003c\/strong\u003e\u003cbr\u003eNo. The dryer, air receiver and filters are designed separately according to the required compressed air quality.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhich version is right?\u003c\/strong\u003e\u003cbr\u003eThe 5–8 bar version delivers the higher air volume. The 5–10 bar version is intended for applications with higher line pressure. The decisive factors are actual consumption, the required minimum pressure and sufficient capacity reserve.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Comprag","offers":[{"title":"8 \/ 15.40","offer_id":51522297856347,"sku":"11300115","price":20647.15,"currency_code":"EUR","in_stock":true},{"title":"10 \/ 13.40","offer_id":51522297889115,"sku":"11300116","price":20647.15,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0876\/8526\/7803\/files\/schraubenkompressor-1-zu-1-direktantrieb-drehzahlgeregelt-dv-90-comprag.jpg?v=1760373789"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0876\/8526\/7803\/collections\/schraubenkompressor-drehzahlgeregelt-fv-45-fv-55-comprag_157bd5fc-5cee-4330-a9c9-453ab44ec951.jpg?v=1780753495","url":"https:\/\/ae6ea8-95.myshopify.com\/en-sk\/collections\/schraubenkompressoren-auf-basisgestell-mit-riemenantrieb-und-drehzahlreglung-kopie.oembed","provider":"ABS Strahltechnik","version":"1.0","type":"link"}
