The flexible suction system, EasyGlide and EasyClean can be stored directly on the unit.
The inlet valve depressor guarantees a high operating reliability. One press of the button and the valve is free.

The perfect airless spray unit - Big enough to spray a large new build interior, sealer and top coats but small enough to be your first choice for all your fine finish applications like finishing doors and windows with either solvent or waterbased paints. 

Provided with both a suction hose and a 3.7ltr gravity hopper, the Wagner SuperFinish SF21 Pro offers convenience for all types of spray painting needs. The suction hose draws paint directly from the can for larger applications, while the gravity hopper is ideal for fine finish work and small colour runs.

Diaphragm pumps have no noticeable pulsation and provide a versatility that make them a perfect all-rounder offering excellent value for money.

The SF21 can be used with a hose as small as 7.5m (ideal when using the hopper to reduce the amount of paint in the line) or join 2 x 15m hoses together and run 30m to give you an impressive amount of reach.

Brushless motor technology makes it ideal for sites with poor power, easily runs off a 3kva or larger generator.

Diaphragm Benefits Include:

Less electronics when compared to piston technology - less to go wrong.

Can be run dry without causing damage to the unit.

Less wearing parts than piston pumps.

Almost completely field serviceable

Will easily handle a wide variety of materials, from thin liquids to high-viscosity paints. QLS technology and low stroke frequency put less stress on the components, significantly extending the service life of the pump and reducing maintenance costs.


Valves are made of wear-resistant carbide and the diaphragm is made of solvent resistant polyamide.


Vector Pro Gun

A revolution in comfort and control. Light-weight trigger pull for less fatigue.

Flexible Suction Hose + Hopper

Comes with both 3.7L hopper and flexible suction hose - making it extremely versatile.
