Throohills HVLP Siphon Set With 1.4/1.7/2.0mm Nozzles
This professional HVLP spray gun set includes three stainless steel nozzles (1.4/1.7/2.0mm) and a 1000cc aluminum cup with a brass airflow cap. It’s designed for smooth, even coating of basecoats and clearcoats, and is compatible with a range of high-viscosity coatings. Best for automotive refinishing and furniture projects requiring multiple spray patterns. A potential limitation is the need for compatible compressors and the learning curve to dial in three nozzles for different coatings.
Throohills Siphon Feed 1.8 mm (Blue)
Designed for smooth, even coating, this spray gun uses a 1.8mm stainless steel nozzle and a 1000cc cup. It features a comfortable ergonomic handle and a 360° adjustable nozzle cap for flexible spray directions. Best for general automotive, furniture, and household painting tasks. Better for projects that require consistent atomization with easier control; however, 1.8mm may be less suitable for very fine finishes at extreme thin-film coatings.
Throohills Siphon Feed 1.8 mm (Red)
This red variant mirrors the blue 1.8mm model with an ergonomic handle and 360° nozzle-cap adjustment. It’s best for users who want comfortable operation across various projects, including cars and furniture. Choose this if you value grip comfort and easy handling; avoid this if you require a finer nozzle for ultra-thin finishes.
ZHONG AN 3.0 mm Pro Gun
Equipped with a 3.0mm nozzle and a 1000cc anti-drip canister, this gun is designed to tackle a wide range of viscosity levels. It minimizes mess with a tight-sealing canister and offers easy control through a robust air valve design. Best for larger, faster coating tasks and coatings with higher viscosity. A limitation is that the 3.0mm nozzle may not provide the finest atomization for ultra-thin finishes.
REFINE HVLP Dual Nozzle 1.7/2.0 mm
REFINE’s gun includes two interchangeable nozzles (1.7mm and 2.0mm) with a nickel-plated aluminum body and a 360° adjustable air cap. It offers three adjustment knobs for spray width, paint flow, and air volume. Best for versatile finishes on cars, furniture, and walls. This model suits users who need quick nozzle switching to accommodate different coatings; watch for alignment when swapping nozzles to maintain consistent atomization.
PNTGREEN HVLP with 1.8 mm
With a 1.8mm nozzle and 1000cc cup, this gun provides a comfortable grip and adjustable controls for liquid flow, air volume, and spray range. It’s well-suited for painting cars, walls, wood, metal, and leather. Best for general DIY projects and intermediate painters. Limitation includes needing proper setup for optimal atomization at very high coating viscosities.
CarBole Suction Paint Gun
CarBole offers three nozzle sizes (1.3/1.7/2.0mm) with a 1000cc aluminum cup and three spray patterns. It’s designed for a wide array of surfaces, from chalk-type paints to clear sealers. Best for DIY furniture and home projects where different spray patterns will be helpful. A potential drawback is the need for a suitable compressor that can meet the airflow requirements for thorough atomization on thicker coatings.
AutoViteX 34 Ounce HVLP Gun
AutoViteX includes a 2.0mm nozzle and a large 34-ounce (1000cc) cup, with adjustable spray pattern and fluid control. It provides a comfortable grip for extended use and a leak-proof cup for cleaner operation. Best for professionals and dedicated hobbyists needing higher capacity and versatile spray control. A limitation is that larger cups can require more careful handling to avoid drips during refilling.
Buying Guide: Key Purchase Considerations
- Nozzle options: More nozzle sizes increase versatility for coatings from primers to fine finishes. Look for sets with 1.3–2.0 mm ranges.
- Cup capacity: 1000 cc cups suit longer projects; smaller cups require frequent refills but can be lighter to handle.
- Air inlet and regulator: Ensure compatibility with your compressor. A built-in regulator helps dial in paint flow.
- Grips and ergonomics: A comfortable handle reduces fatigue on long sessions and improves control for even coatings.
- Anti-drip features: Anti-drip cups minimize waste and mess, especially with high-viscosity materials.
- Maintenance: Look for solid stainless steel components and simple disassembly for cleaning to extend life.
FAQ
- What is HVLP and why choose siphon feed?
HVLP (high-volume, low-pressure) provides better transfer efficiency, reducing overspray. Siphon feed models are typically easier to clean and offer wide pattern options. - Can I spray automotive clear coats with these guns?
Yes, many models are suitable for basecoats and clearcoats, but verify nozzle size and volatility for the specific coating you use. - Do I need a powerful compressor?
A stable, adequate air supply is important. Check the required CFM and ensure your compressor meets or exceeds it for consistent atomization. - Are 1000cc cups leak-proof?
Most 1000cc cups are designed to be leak-resistant, but proper tightening and gasket condition are key for preventing leaks. - Which nozzle should I start with?
For fine finishes, start with 1.3–1.8mm; for thicker coatings and primers, 2.0–3.0mm can be more effective. Adjust based on spray results. - Is cleaning necessary after each use?
Yes. Thorough cleaning prevents clogging and preserves spray quality. Use the included brushes and cleaners as applicable.
