Description
Product Overview
The iFJF R18189-30 Spin-On Fuel Filter is a heavy-duty 30-micron filter designed for mobile and stationary diesel applications. Featuring a standard 1-inch NPT port, this spin-on filter provides reliable primary fuel filtration for generator sets, fuel transfer systems, mobile refueling equipment, and stationary diesel engines. The 30-micron rating makes it ideal as a primary filter before finer secondary filtration. Robust construction for demanding industrial and mobile service.
Key Features
-
30-Micron Primary Filtration: Optimal for first-stage filtration — catches larger particles and debris before they reach finer secondary filters downstream.
-
1-Inch NPT Port: Industry-standard thread for easy integration with fuel transfer pumps, generator fuel systems, and bulk filtration setups.
-
Spin-On Convenience: Quick-change design — no housing to disassemble, just spin off the old filter and spin on the new one.
-
Mobile & Stationary Compatible: Suitable for fuel transfer trailers, generator sets, agricultural equipment, construction machinery, and stationary diesel engines.
-
Heavy-Duty Construction: Reinforced canister designed for high flow rates and continuous duty in industrial applications.

Frequently Asked Questions
Q: Is 30 micron enough for diesel engines?
A: 30 micron is ideal for primary (first-stage) filtration. It should be paired with a finer secondary filter (10 micron or less) before the injection pump for complete protection.
Q: What's the 1-inch NPT connection for?
A: The 1-inch NPT port fits standard fuel transfer pump plumbing, generator fuel systems, and industrial diesel setups with NPT-threaded fuel lines.
Q: Can I use this for gasoline?
A: This filter is designed for diesel fuel applications. Verify compatibility before using with gasoline or other fuels.
Q: How often should this filter be replaced?
A: Monitor the pressure gauge across the filter head. Replace when pressure drop exceeds 8-10 PSI, or every 500 hours of operation — whichever comes first.
Q: Does this filter separate water?
A: The primary function is particulate filtration at 30 microns. For water separation, pair with a dedicated water separator or use a filter with coalescing media downstream.
