Summary

This video explains how to identify, inspect, and replace filters on a Compact spray machine. Proper filter maintenance ensures correct airflow, effective overspray removal, and consistent finish quality.

Quick Guide

When to Change Filters

  • Poor airflow or “machine not breathing”

  • Excess overspray inside the cabin

  • Paint collecting on ceiling filters

  • Intake fan speed increasing above 80–90%

Top Exhaust Filters (Accordion Filters)

  1. Located at the top of the machine.

  2. No tools required.

  3. Slide out and replace.

  4. Typically changed daily.

  5. Consider changing between primer and topcoat.

Sub-Filters (Fiberglass)

  • Located beneath accordion filters.

  • Change approximately every other day (2:1 ratio with accordion filters).

  • Frequency depends on usage.

Ceiling Filters

  • Two densities:

    • Dense filters on the sides and over filter areas

    • Less dense filters in the center over the conveyor belt (higher airflow)

  • To replace:

    1. Work from the operator side.

    2. Move the reciprocator out of the way.

    3. Lift filters up and out.

  • These are changed less frequently than accordion filters.

  • Paint on ceiling filters indicates restricted airflow below.

Intake Air Adjustment

  • Start shifts at 30–40% intake fan speed.

  • As filters load, intake speed may increase.

  • At 80–90%, replace accordion filters and reduce fan speed.

Atmospheric (Intake) Filters

  1. Located where air enters from the room.

  2. Pull out and replace — no tools required.

  3. Change frequency depends on room cleanliness:

    • Dusty environments → change more often

    • Clean rooms → change less often

Key Notes

  • Overspray on ceiling filters is a warning sign.

  • Proper filter maintenance improves airflow, finish quality, and machine performance.
