Core Airless Sprayer Technology
2200W Brushless DC Motor, 2.5 L/min, 0.021 in Tip
A 2200W brushless DC motor drives a piston-type fluid section, supplied in a Dual-Ceramic Version (ceramic-coated rod and ceramic-lined cylinder sleeve) or a Stainless Steel Version, delivering up to 2.5 L/min for water-based latex, acrylic and primer coatings on walls.
Dual-Ceramic or Stainless Steel Pump
2.5 L/min fluid sectionMachined on Japan Brother SPEEDIO CNC centers, this fluid section is offered as a Dual-Ceramic Version (ceramic-coated rod, ceramic-lined cylinder sleeve with stainless shell and ceramic bore) or a Stainless Steel Version (stainless steel rod, stainless steel cylinder liner). Maximum flow rate 2.5 L/min, maximum tip size 0.021 in; ±0.01 mm tolerance applies only to critical machined metal mating surfaces.
Brushless DC Motor
2200 W brushless DC motorPowered by a 2200W brushless DC motor: consistent torque, high running efficiency and no carbon-brush wear. Rated for single-gun operation. Motors and control PCBs are made in-house; every PCB runs a 4-hour powered burn-in before assembly and every finished sprayer a 30-minute continuous high-pressure load test.
Electronic Pressure Control and Display Screen
Up to 3,300 PSI, 0.021 inRated at 3,300 PSI (227 bar / 22.7 MPa) Max. Working Pressure with support for up to a 0.021″ spray tip and 2.5 L/min maximum flow. Working pressure is visible on the display screen, which has an English-language interface, and overheat protection is built in.
Material Compatibility of this GTB-595 airless paint sprayer
Whether a coating can be sprayed depends on the spray tip orifice size, flow rate and pressure, together with the viscosity of the coating. Rated values for this sprayer: maximum spray tip size 0.021″, maximum flow rate 2.5 L/min, Max. Working Pressure 3,300 PSI (227 bar / 22.7 MPa). For any specific coating, follow the coating manufacturer’s technical data sheet (TDS).

Why Choose the GTB-595 Airless Sprayer
Single-gun airless spraying of interior and exterior latex paint, acrylic wall paints and emulsions, water-based enamels and primers.
The GTB-595 is an airless paint sprayer with a 2200W brushless DC motor, 2.5 L/min maximum flow, 0.021 in maximum tip and 3,300 PSI (227 bar / 22.7 MPa) Max. Working Pressure, with overheat protection and working pressure shown on an English-language display screen. Pump body, motor and control PCB are made 100% in-house. Pump bodies, aluminum housings and filters are machined on Japan Brother CNC centers; connecting rods, pistons and plunger bores on USA Haas CNC centers.
How Electronic Pressure Control Works
Pressure is set on a potentiometer. A pressure sensor reads the actual pressure; the main control board compares that reading with the set value and drives the motor accordingly.

What is the GTB-595 built for?
The GTB-595 is a 2200 W brushless DC unit rated at 2.5 L/min with a 0.021 in maximum tip size. It is specified for water-based architectural coatings: latex, acrylic, water-based enamels, primers and sealers on walls and ceilings.
What tip ships with the GTB-595, and what is the maximum tip size?
A 621 spray tip is supplied, and the maximum rated tip size is 0.021 in. Under typical industry tip numbering, a 621 denotes a .021 in orifice and roughly a 12 in fan at a 12 in gun distance.
Can the GTB-595 spray primers, stains and clear coats?
Yes, water-based ones: water-based primers and PVA drywall sealers, waterborne wood stains (solid and semi-transparent), and water-based clear coats, sealers and topcoats are all in the sprayable class. Oil-based primers and stains, varnishes and polyurethanes are conditional and need the coating data sheet plus flammable-material precautions.
Which pump versions of the GTB-595 are available?
Two. Stainless Steel Version: stainless steel rod and stainless steel cylinder liner. Dual-Ceramic Version: ceramic-coated rod and ceramic-lined cylinder sleeve (stainless shell, ceramic bore). Motor, flow and pressure ratings do not change between versions.
What testing does each GTB-595 pass before packing?
100% inspection. The PCB is powered for a 4-hour burn-in, the assembled sprayer runs a 30-minute continuous high-pressure load test, and first-article, in-process and final inspections cover each unit.
