Designed for heavy-duty truck, farm and industrial applications, System 1’s 800 series assemblies measure 9-1/4“ long by 5” in diameter. They can easily pay for themselves when compared to purchasing many disposable filters. And from a business perspective, you can reduce inventory levels, disposal costs, etc. If there is room, you may want to consider the extra capacity that comes with the 12-1/4” long Series 900 filters. All are available with either 35-micron or 75-micron stainless steel mesh elements and have the popular 1-1/2” – 12 thread.
