Wagner SuperFinish 21 Pro HEA Airless Diaphragm Paint Sprayer

What jobs is the Wagner SuperFinish 21 Pro HEA paint sprayer suited for?

The Wagner SuperFinish 21 Pro HEA paints walls and ceilings with the airless method using dispersion and latex wall paints, and it also sprays adhesives and sealants. The manufacturer quotes an optimal output of 600 m² per day with wall paints and work up to 5 times faster than with a roller. The diaphragm pump has a service life of 50,000 - 70,000 m², so the sprayer copes with regular work on site. Water-based and solvent-based paints, lacquers, oils and protective coatings need additional accessories that the manufacturer provides for this model.

What is HEA technology and what does it do when painting walls?

HEA (High Efficiency Airless) is a Wagner technology in which the pump works at a lower spraying pressure than in classic airless sprayers. According to the manufacturer the spray is gentler and overspray is reduced by up to 55%, which limits soiling of the surroundings. The SuperFinish 21 Pro HEA reaches a maximum of 207 bar and 2.1 l/min, and the manufacturer says the diaphragm pump holds up to 58% less material, so cleaning takes less time. The motor is brushless, and the inlet and outlet valves can be replaced on site.

What tip and hose come with the Wagner SuperFinish 21 Pro HEA?

The set includes the sprayer with a suction system, a 15 m pressure hose, a VectorPro spray gun, an HEA ProTip 517 tip, a white finger filter and an HEA pressure gauge. The maximum tip size is 0.021" and the maximum flow rate is 2.1 l/min, so the tip is chosen for the paint and fan width within those limits. The VectorPro gun has an ergonomic grip and can be taken apart for cleaning. Additional tips from the HEA ProTip series are sold separately.

What power supply and motor power does the Wagner SuperFinish 21 Pro HEA have?

The sprayer is electric and runs on 230 V at 50 Hz. The brushless motor delivers 0.9 kW and drives a diaphragm pump with a flow rate of up to 2.1 l/min and a working pressure of up to 207 bar. The unit weighs 23.6 kg and the pressure hose is 15 m long, so you can paint a large room without moving the sprayer. The unit is not explosion-proof, so it is not used in areas at risk of explosion. The sprayer does not come on a cart.

How do you clean and service the Wagner SuperFinish 21 Pro HEA?

The manufacturer states that the small internal diameter of the pump and hose shortens cleaning and reduces the amount of cleaning fluid needed. The inlet and outlet valves can be replaced on site, and wear parts are easy to replace. The diaphragm pump has a service life of 50,000 - 70,000 m² of painting, and the brushless motor needs no brush replacement.

The SuperFinish 21 Pro HEA is the smallest HEA diaphragm sprayer in the Wagner range: pressure up to 207 bar, flow rate 2.1 l/min, tip up to 0.021" and a 0.9 kW motor. The SuperFinish 23 PRO reaches 250 bar and 2.6 l/min, takes a tip up to 0.023" and has a 1.3 kW motor, so it has more pressure and output in reserve. Both come with a 15 m hose.
