Change the oil regularly — if it appears milky white, it has been left too long. Check and empty the moisture trap near the output regulator when full. After each use, release compressed air from the tank to prevent condensation buildup that can cause internal rust. These steps protect the pump, internal components, and tank from water damage.\u003c\/p\u003e","brand":"Otto Frei","offers":[{"title":"Default Title","offer_id":43579931525334,"sku":"123.096","price":1591.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/super-silent-val-air-50-15al-air-compressor-12-hp-4-gallon-tank-otto-frei.jpg?v=1719958355","url":"https:\/\/www.ottofrei.com\/it\/products\/val-air-50-15al-super-silent-air-compressor-half-hp-4-gallon","provider":"Otto Frei","version":"1.0","type":"link"}
