Airless technology has revolutionised the world of spray painting, giving professionals a tool that combines speed of execution, finish quality and reduced waste. Thanks to the absence of compressed air and the high pressure generated by the pump, the paint is atomised uniformly and precisely, guaranteeing accurate, optimised applications even on complex or hard-to-reach surfaces.
However, to unlock the full potential of an airless system, it is important to know and select the right accessories: spray tips suited to the type of paint, kits to keep the gun efficient, filters and valves to protect the system from impurities, safe and durable high-pressure hoses, right through to advanced accessories such as the Airless Revolver, which optimise comfort, performance and control.
Why accessories (too) make the difference in airless painting
In airless painting, the quality of the final result also depends on the choice and maintenance of the accessories. Tips, filters, repair kits, hoses and valves are fundamental for keeping the system’s output high, reducing consumption and guaranteeing uniform finishes.
Using original accessories, designed to work in synergy with Tecnover pumps, means guaranteed operational efficiency, long equipment life and greater safety at work. Conversely, using generic spare parts or worn components can lead to problems well known to professionals in the trade: irregular spray, runs, overspray, pressure drops or even gun blockages during application.
Among the most common mistakes are using tips unsuited to the type of paint or already worn out, as well as clogged filters or filters with the wrong mesh, which compromise spray quality and increase waste.
These problems can be prevented – and in the following sections we will see how.
Choosing spray tips: the heart of airless performance
Tip size and type
The spray tip is a small but decisive component in determining the quality of the final result, since it defines flow rate, spray fan width and required pressure, directly influencing consumption, coverage and finish.
The tip size consists of three digits:
- The first indicates the spray angle (multiplied by 5, it gives the fan width at a distance of 30 cm).
- The last two indicate the orifice size in thousandths of an inch, and therefore the flow rate.
In practice, the denser the material to be sprayed (such as waterproofing membranes or quartz paints), the larger the tip orifice needs to be. Conversely, this means that for lighter products (enamels, fine coatings) you will use tips with smaller orifices. A few examples:
- Enamels on wood or metal: 0.009″ – 0.015″
- Interior wall painting: 0.017″ – 0.023″
- Siloxane or exterior paints: 0.023″ – 0.027″
- Airless fillers: 0.019″ – 0.021″
- Membranes and intumescent coatings: 0.023″ and up
Remember: every airless pump has a maximum supported tip size. Always check the technical data sheet and, if in doubt, consult a Tecnover technician.
Tecnover tips: uniformity and precision in airless painting
Original Tecnover tips are designed to deliver uniform spray patterns, controlled atomisation and fewer runs. Available in different versions, they meet a wide range of application needs thanks to a perfect balance between flow rate and spray angle.
Made with a tungsten carbide insert – a material renowned for its exceptional wear resistance – they ensure a long service life even with abrasive paints or high-viscosity products.
Two versions worth highlighting:
- Fine Finish (white guard): with integrated pre-atomiser, ideal for premium finishes and low-pressure applications.
- Low Pressure (green guard): guarantees optimal atomisation at pressures up to 50% lower than standard, reducing pump wear, overspray risk and paint consumption.
For more information on choosing airless tips and best practices for getting the most out of these components, see our dedicated guide on the Tecnover website.
Maintenance kits for airless guns: a guarantee of continuity
Included components: seals, seats, filters, valves
An airless gun in optimal condition is essential for a uniform, constant, uninterrupted spray. Tecnover accessories include all the critical components that inevitably wear or deteriorate over time:
- Seals: ensure the system is watertight, preventing paint leaks.
- Sleeve and needle: control the opening and closing of the flow and keep the pressure stable.
- Filters: protect the tip and gun from impurities and particles that could clog the system or compromise atomisation.
Using original kits guarantees full compatibility with the structure of the Tecnover airless gun, avoiding problems such as leaks, pressure drops or spray instability. Even a simple worn seal can cause visible defects in the final result or increase material consumption (and therefore waste).
By contrast, a well-chosen maintenance kit extends the life of the equipment and ensures consistent professional performance, even in the most intensive work cycles.
Preventive maintenance: small habits, big benefits
Preventive maintenance is a simple but fundamental practice for avoiding machine downtime, performance drops and unnecessary material consumption.
Good habits include:
- Thorough cleaning after every use, with solvents or water depending on the type of paint used.
- Regular lubrication of moving parts, to prevent friction and preserve smooth movement.
- Scheduled replacement of seals, filters and valves, according to frequency of use and the type of product sprayed.
The result? Fewer unexpected failures, longer gun and tip life, excellent spray uniformity even after hours of work, and consistent, defect-free finishes. In short, taking care of your airless gun means working better, for longer, with fewer surprises: proper maintenance is the best investment for anyone using airless technology every day.
Airless Revolver: the accessory that changes the way you spray
In an industry where every second counts, the Airless Revolver system introduces a simple but revolutionary change: the ability to rotate the spray fan 90° with a single flick, without dismantling the gun, without tools and without interruptions.
At the heart of the innovation is a patented poly-magnetic mechanism, designed to automatically lock the position at every click, giving the operator maximum control with minimum effort.
With the Airless Revolver, you get:
- Instant adaptation from vertical to horizontal surfaces.
- Continuous workflow, with no dead time.
- Improved ergonomics: less strain on wrists, arms and shoulders.
- High performance even in tight spaces or awkward positions.
The accessory is designed for those who work with airless systems every day and are looking for tools that are even more intuitive, faster and more precise. A tangible evolution of the spray gun concept, developed to increase comfort, speed and work quality.
Available versions
The Revolver range consists of two complementary solutions, designed to suit any operational need:
- Airless Revolver: a complete professional gun with integrated rotating fan, available with ¼″ or 16×1.5 connection, in a European version (11/16″ thread) and an American version (7/8″ thread).
- Airless Fan Revolver: the accessory compatible with most airless guns already on the market. It adds magnetic rotation without replacing the gun, delivering the same operational convenience.
Both versions are made from tough, lightweight materials (aluminium and glass-fibre-reinforced nylon), are compatible with water-based and solvent-based paints and are easy to clean without dismantling.
Practical applications
The Airless Revolver comes into its own wherever speed, adaptability and precision are essential to complete professional jobs in less time and with consistent results. We are talking about sectors such as construction, steelwork, joinery, manufacturing and the marine industry, where switching from one surface to another – vertical, horizontal or inclined – happens constantly and without warning.
It is precisely in these scenarios that the difference between a traditional gun and Airless Revolver technology becomes clear. With the Airless Revolver, the fan orientation changes instantly, with a simple flick of the finger, with no need to dismantle the gun or interrupt the workflow. This translates into greater operator comfort, less fatigue on wrists and arms, and a more fluid, precise application.
By contrast, every change of orientation with traditional guns requires stopping work, using tools and greater exposure to errors or spray discontinuity. This inevitably means longer times, more fatigue and potentially compromised quality when transitioning between different surfaces.
The Airless Revolver therefore improves efficiency, simplifies movements and keeps finish quality high, even in dynamic, complex working conditions. A smart solution for anyone who sprays for a living and cannot afford to slow down.
Filters and hoses: invisible but indispensable accessories
In a professional airless system, even the less visible components such as filters and hoses play a fundamental role in the quality and continuity of the work.
Gun filters and inlet/outlet filters
Before reaching the tip, the paint must pass through a series of filters designed to trap impurities, lumps or dried residues that could compromise atomisation. Tecnover filters are available in different mesh sizes, calibrated to the density and particle size of the product used:
- 100 mesh / 150 mesh: ideal for enamels and light paints.
- 200 mesh / 300 mesh: suited to ultra-fine finishes and highly fluid paints.
- 30 mesh / 50 mesh: recommended for dense paints, resins, membranes, quartz products or encapsulants.
Selecting the right filter, both at the pump inlet and directly on the gun, protects the entire system from clogging, reduces tip wear and guarantees continuous, clean atomisation. It is good practice to clean the filters regularly and replace them as soon as you notice flow drops or irregular spraying.
High-pressure and anti-vibration hoses
High-pressure hoses can be considered the “backbone” of the airless system: they carry the paint from pump to gun and must guarantee maximum strength, sealing and compatibility with materials that are often very dense or abrasive. That is why they are made with an internal steel braid instead of the common textile braid, ensuring maximum safety against both external abrasion from rubbing on wall edges and accidental crushing underfoot on site.
Tecnover offers professional solutions built to withstand the high pressures required by airless systems (up to 250 bar), also available in anti-vibration versions that reduce operator fatigue, especially on long jobs or work at height. The benefits:
- Safety: no risk of sudden rupture.
- Durability: materials resistant to abrasion and chemical agents.
- Comfort: fewer vibrations mean more control and less physical strain.
The quality of the hose has a direct impact on pressure stability and spray precision: a factor not to be underestimated, either at purchase or during maintenance.
