Inlet Filter GRACO 3/4" – GRACO, model 183770, inlet filter for fluid systems

GRACO inlet filter 3/4" model 183770 is an inline fluid inlet filter designed for use in industrial and commercial fluid handling systems. It removes particulates from incoming fluid to protect pumps, valves and control components in spray equipment and coating systems. The filter is intended for installation at the fluid inlet to reduce contamination-related wear and help maintain consistent equipment performance in paint sprayers, pumps and related machinery.

Advantages

The inlet filter provides mechanical particle retention to limit abrasive wear in downstream components and minimize clogs in spray tips and control valves. Its 3/4" inline design enables straightforward integration into existing fluid lines with minimal modification. By preventing contaminant entry, the filter contributes to longer service intervals and more predictable spray and pump behavior without changing the core equipment design.

Suitable for

• Paint sprayers and spray guns in industrial and commercial painting
• Fluid pumps and reciprocating equipment requiring particulate protection
• Coating application systems and transfer lines for solvents, coatings and similar fluids
• Maintenance kits or system upgrades where inline filtration is needed at the fluid inlet

Key specifications

• Connection size: 3/4" inline inlet
• Function: particulate filtration for inlet fluid stream
• Application area: fluid handling and spray/coating systems
• Mounting: inline installation at fluid inlet of pump or control assembly

How to use

Install the inlet filter in the fluid supply line upstream of the pump or control components, ensuring correct flow direction. Secure connections according to the system's standard fittings and torque specifications. Inspect and clean or replace the filter element according to operating conditions and manufacturer maintenance intervals to avoid pressure drop or flow restriction. When handling solvent-based fluids, follow safety procedures for flushing and purging lines before service.

Usage recommendations

Inspect the filter during regular maintenance intervals and after any contamination events. Replace the filter element if pressure drop increases or if visible clogging occurs. Use appropriate personal protective equipment and follow fluid-specific handling guidelines when servicing the filter to maintain safe operation of the fluid system.
