Graco 15G649 Filter Base

Base Filter Assembly – Model 15G649

The 15G649 BASE, FILTER is an OEM-engineered filter base manifold designed to integrate the main fluid filter into your high-performance spray system. It provides a reliable mount for the filter cartridge and ensures proper fluid channeling, structural integrity, and system cleanliness in demanding environments.

Applications & Fitment

This filter base is used in large-capacity cart-mounted sprayer systems, supply manifolds and modular filter stacks. It is listed in parts catalogs for selected models of industrial coating sprayers and provides a robust platform for mounting the fluid filter, drainage kit and necessary fittings.

Key Specifications

Product Highlights

• Heavy-duty mounting structure to secure the filter cartridge under high fluid pressure and flow.
• Precisely machined fluid channels within the base to maintain optimal flow characteristics and minimise turbulence.
• Integrated ports for “drain kit” and gauge mounting, enabling easy servicing and monitoring of the filter condition.
• Direct OEM replacement part to restore original system design, look and function.

Installation Guidelines

Before installing the 15G649 base, relieve equipment pressure and isolate the fluid supply. Remove the old base or filter assembly, clean the mounting surface and check for damaged thread ports or seals. Mount the new base using correct hardware, install the filter cartridge, connect the drain kit and any gauges, then verify there are no leaks and that fluid flow is unobstructed before returning the system to service.

Maintenance & Care

• Regularly inspect the base for leaks, corrosion or damage at the mounting and port interfaces.
• Whenever the filter cartridge is replaced, check the drain port plug, gauge port threads and sealing surfaces for debris or wear.
• Keep the area around the base clear of paint/filler overspray and buildup to maintain easy access and clean service procedures.
