Product detailed description
SGM502 spray gun - the professional solution for large-scale painting with external paint reservoir
The SGM502 is designed for professionals looking for an effective and durable solution for intensive spraying of larger areas without the need for constant refills. The gun uses a High Volume Low Pressure (HVLP) system that guarantees high transfer efficiency with minimal waste and excessive paint dispersion.
Unlike conventional guns with upper or lower canister, the SGM502 is designed for direct connection to an external paint reservoir - using a material hose with G1/4" thread. This solution is ideal when spraying large surfaces where the volume of a conventional gun canister is insufficient or would put unnecessary strain on the operator's hand.
The body of the gun is made of durable die-cast aluminium, which makes it robust and relatively lightweight at the same time. The silicone-free design also allows use in applications with high demands on environmental cleanliness, such as painting plastics, automotive parts or wooden furniture.
The gun is equipped with precise control of colour, air and beam shape, allowing ideal adaptation to the specific material and working conditions. The air connection is made with a standard DN7.2 quick coupling, so it can be easily connected to an existing pneumatic system.
Using the SGM502 gun:
-
large-scale painting of structures, furniture, doors, panels, etc.
-
spraying in industrial production, joinery and metalworking
-
suitable for base and top coats - acrylic, synthetic, waterborne and 2K paints
-
plants where paint is dispensed from a pressure tank or pump
💡 Tip: For a flawless result, we recommend using dry and clean compressed air according to ISO 8573-1. Everything you need can be found in our Air Conditioning section.

Black Wind is a Czech brand of tools and accessories for working with compressed air. We offer Black Wind blow guns, spray guns and sandblasting guns, tyre inflators, air tools, hoses, compressor parts and a range of small compressors.
The products are made for DIY users and tradespeople: for the garage, home workshop, car service and paint shop. Most guns, inflators and tools have a DN 7.2 nipple, so they plug straight into a standard quick coupling on the hose or compressor.

How to connect a gun or tool
1. Compare air use
Air consumption is listed in the specifications of every product. Compare it with the compressor’s free air delivery, the air the machine actually supplies, not with its intake capacity.
2. Set the pressure
Use the regulator on the compressor to set the pressure for the product: Black Wind air tools work at 6.3 bar, HVLP and LVLP spray guns from 2 bar.
3. Connect
Most guns and tools have a DN 7.2 nipple that fits a standard quick coupling. ABGP guns have a 1/4" female thread, so you screw in a nipple separately.
4. After work
Clean the spray gun straight away with a cleaner suited to the type of paint. Drain the condensate from the compressor and check the oil sight glass on oil-lubricated machines.
Frequently asked questions
- What compressor do I need for a spray gun?
- It depends on the gun’s air consumption. The SGH1002 LVLP gun uses 150 l/min, the SGHX100 APS gun 200 to 400 l/min and the SGM502 for an external tank 350 to 450 l/min. For occasional spraying of small items a 24 l tank is enough; for larger surfaces plan on 50 l.
- What is the difference between HVLP, LVLP and APS?
- HVLP works with a high volume of air at low pressure and saves paint. LVLP atomises paint finely with lower air consumption, so it suits smaller compressors. APS has the benefits of HVLP but works at a higher pressure and handles thicker paints.
- Which tyre inflators are certified?
- The TG-63C, TG-63D, TG-80C and TG-80DC are certified to EN 12645:2014. Models with a D have a twin chuck on an extension for dual truck wheels; the TG-80C and TG-80DC come with a test report.
- How do I change the nozzle of a blow gun?
- Nozzles on ABG, ABGP and ABG03 guns screw in with a G 1/4" thread. Unscrew the old nozzle and tighten the new one. For ABG guns we offer spare nozzles of 30, 100 and 300 mm.
- What is the BW-0002 pressure switch for?
- It switches the compressor motor on and off according to the pressure in the tank. From the factory it cuts in at 6 bar and cuts out at 8 bar, withstands up to 12 bar and is for single-phase 230 V motors up to 15 A. If the switch fails to cut out, the BW-0008 or BW-0009 safety valve protects the tank.
- How often should I change the oil and intake filter?
- The original BWL-1 mineral oil is changed once a year or every 100 operating hours, whichever comes first. Black Wind intake filters have the same interval; change them more often in a dusty workshop.
Service and original spare parts for Black Wind compressors are available in the Czech Republic and Slovakia. An operating manual and a catalogue sheet in Czech can be downloaded with every Black Wind compressor. Pressures and air consumption in this text come from the specifications of the individual products.
