Black Sponge-Wrapped Air Filter Element 150x340

This Black Sponge-Wrapped Air Filter Element is a two-stage filter in one body. The outer layer is a black polyurethane sponge—open-cell, oil-resistant, and washable. Its job is to stop bugs, leaves, sand, and other large particles before they ever reach the inner filter. The inner element is a high-density pleated paper or non-woven media that catches the fine dust that the sponge lets through. When the sponge gets dirty, you pull it off, wash it, dry it, and put it back. The inner element lasts much longer because the sponge takes the abuse. This 150x340 size is common in medium-to-large air compressors, diesel generators, construction equipment, and agricultural machinery. If you’re tired of buying expensive OEM filter kits every month, this is your replacement.
