UG4000D Series Spray Gun Washer

Professional Performance for Paint Shops and Collision Centers

Painters who invest in high-end spray guns trust the UG4000D Spray Gun Washer to protect their tools. The UG4000D is engineered for maximum cleaning efficiency, combining automated wash, air rinse, and clean rinse cycles with manual flow-through brushing to remove hardened overspray—ideal for busy, high-throughput environments.

Key Features:

• Top Loading Design
  Cleans two spray guns in under two minutes using an efficient, hands-free process.

• Stainless Steel Construction
  The wash tank, measuring 17.25″ W × 13.5″ D × 14″ H, is built from corrosion-resistant stainless steel for enhanced durability.

• Powerful Cleaning System
  Equipped with a 4″ dual-diaphragm pump delivering 3.7 gallons of solvent per minute. Cleaning is activated by an adjustable wash timer.

• Foot Pedal Operation
  The flow-through brush is powered by a 2″ dual-diaphragm pump (1.9 gal/min), providing manual control for precise washing.

• Effective Solvent Delivery
  Mounting adapters fit popular conventional and disposable cup systems to ensure deep cleaning of the paint channel. Fourteen swirl action jets deliver solvent to wash the gun’s exterior.

• Safety Features
  The pump halts instantly if the lid is raised during operation, reducing solvent exposure risk. A stainless steel mesh filter keeps solvent clean and protects the pump from debris.

• Enhanced Airflow System
  A plastic cone blocks solvent from entering the air passage and ensures continuous air movement to the gun cap.

• Fume Extraction System
  The UG4000D is the first spray gun washer in Uni-ram’s series to include a built-in fume extractor that automatically removes solvent vapors when the lid is opened.

• Robust Lower Cabinet
  Constructed from powder-coated mild steel, featuring a secure closing door, integrated floor, leveling feet, and a drain valve to prevent spills when refilling the pail.

• Complete Kit Included
  Supplied with one solvent wash pail (inside the cabinet), trigger clamps, and standard operating procedures (SOPs).
  CE Approved.
