InoKraft D1 LVLP Air Spray Gun Premium Kit, Easy to Use, Paint Gun for Cars & House DIY Painting, 1.3/1.5/1.7mm Nozzles, with Paint Sprayer Accessories

I set the D1 on my bench with the intention of giving it a fair shake across a full refinish workflow: high-build primer, base, and clear on an older hood and a few furniture panels. By the end of the weekend, I’d formed a pretty clear view of where this LVLP kit shines, where it compromises, and who will get the most out of it.

Setup and what’s in the kit

As a starter bundle, the D1 kit is thoughtfully complete. Out of the case, you get three nozzle/needle sets (1.3, 1.5, 1.7 mm), a pressure regulator, an oil‑water separator, and a quick‑start guide in addition to the full manual. The body has labeled scales on the fluid and fan knobs, which sounds minor but makes first-time setup faster and repeatable. I appreciated how quickly I could go from “zero” to a tuned pattern on a test card.

The included regulator and separator are convenient for getting up and running without shopping for extras. That said, I’d treat the regulator more as a baseline than a precision instrument. Mine regulated consistently, but compared with a known-good gauge it read a few PSI off. The separator did its job, though I spotted a faint weep around the bowl threads out of the box—easily addressed with a reseat and a dab of thread sealant, but worth checking before you start.

If you use disposable cup systems, my kit included an adapter that fit PPS 1.0‑style cups, which saved time during color changes and cleanup. If your box doesn’t include that adapter, the gun uses a standard connection, so sourcing one isn’t difficult.

Build quality and ergonomics

The D1’s one‑piece forged aluminum body with a Teflon coating is a strong point. It feels rigid, the threads are clean, and the finish resists the usual solvent stains. After a few cycles of primer, base, and clear, a wipe with reducer brought it back to new. The trigger pull is smooth with a clear engagement point; there’s enough spring resistance to be precise without being fatiguing.

Weight and balance are comfortable, especially with a smaller cup. With a full-size cup, the gun remains manageable, but on larger jobs you’ll notice the weight shift. The control knobs have positive detents and the labeling removes guesswork when you’re bouncing between materials.

Air requirements and dialing in

As an LVLP gun, the D1 is friendly to modest shop compressors. I ran it on a unit that delivers about 10 CFM at 90 PSI, and it kept up without drama. My working pressures at the gun were:

• Basecoat: around 20 PSI
• Clearcoat: 26–28 PSI
• High‑build primer: 24–26 PSI (with the 1.7 mm setup)

These numbers aren’t universal—viscosity, temperature, and product choice matter—so treat them as a starting point. The D1’s fan control offers a broad range, from a tight spot pattern to a wide, even fan. The fan stayed stable across the overlap, which made panel-edge blending predictable.

Atomization, transfer efficiency, and finish quality

This is where the D1 impressed me for the price. With the 1.3 mm setup, I got crisp atomization on solvent base and mid‑solids clear at the pressures above. The fan pattern is uniform with a clean gradient at the edges, which translated into:

• Minimal dry spray when I respected gun distance (about 6–7 inches off the panel)
• Very little orange peel with clear laid wet‑on‑wet
• Noticeably lower overspray compared to an older gravity HVLP I keep as a backup

Transfer efficiency felt high. I was able to cover big panels while using less material than I expected, especially with basecoat, and I didn’t fight runs. If you’re moving from HVLP, expect a cleaner booth floor and better mileage out of each mix.

Nozzle choices and material coverage

• 1.7 mm: Excellent for surfacer and high‑build primer. I ran two medium‑wet coats with good flow‑out and no “sandpaper” texture, provided I strained the primer and gave it a touch of reduction within the product’s spec.
• 1.5 mm: Good middle ground for sealers, thicker basecoats, or single‑stage on smaller parts. It also helps if your clear is on the thicker side but you don’t want to bump pressure.
• 1.3 mm: My go‑to for base and clear. It laid down metallics evenly without mottling when I kept my passes consistent and overlapped by about 70%.

Swapping needles and nozzles is straightforward, and the machining on my primary 1.3 set was clean and blemish‑free. I did inspect the spare air caps before use—a habit I recommend with any budget kit. If you see obvious tool marks in the orifices, ask for a replacement before you pull the trigger on a finish coat.

Cleaning and maintenance

The Teflon-coated body makes a difference. Overspray doesn’t cling the way it does on bare aluminum guns, and a reducer‑damp cloth did most of the work. Breaking the gun down between materials was quick, and I didn’t encounter stuck threads or burrs. The kit doesn’t reinvent the wheel here, but it avoids the classic pitfalls that drive you to a drawer for spare seals.

If you spray daily, invest in a better gauge and keep spare seals in the drawer. If you spray occasionally, the included accessories should carry you a long way.

Cup options and workflow

The stock cup size is fine for small panels and tight spaces. On larger panels or full bumpers, I preferred a larger cup or a disposable system to minimize refills. If you regularly spray wide hoods or trucks, plan for a bigger reservoir; it speeds up your workflow and keeps your overlap rhythm consistent.

Limitations and quirks

• The included regulator is usable but not lab-grade. Calibrate against a known-good gauge and write down your offsets.
• Check the oil‑water separator for leaks before painting; reseating the bowl or a fresh O‑ring usually sorts it.
• Quality control on secondary caps can vary. Inspect them—especially the air cap front face and threads—before a critical job.
• While LVLP reduces overspray and air demand, it’s not magic. You still need proper filtration, ventilation, and PPE.

None of these are deal‑breakers, but they’re the places where the price point shows.

Tips for best results

• Strain every material and mix to specified viscosity; this gun rewards clean, consistent feed.
• Start your fan wide open, then tune fluid flow until you get a wet, non‑sagging pass on a test panel.
• Work around 6–7 inches off the surface with 60–70% overlap and a steady pace.
• For clear, err on the side of slightly higher pressure rather than too low; the D1’s atomization tightens up smartly.
• Keep the gun moving and trigger off at the end of each pass to avoid edge build.

Who it’s for

The D1 makes a strong case for DIYers, weekend restorers, and small shops that want quality results without investing in a high‑end pro gun. It’s also a sensible backup or dedicated primer/base/clear tool for semi‑pros who value swapping materials fast by leaving each gun set up with a specific nozzle. If you’re running a high‑volume production line where absolute accessory precision and zero‑tolerance QC are mandatory, you’ll still want your top‑tier workhorse. For almost everyone else, this is plenty of gun.

Recommendation

I recommend the D1. It delivers clean atomization, an even fan, and real paint savings while running comfortably on mid‑sized compressors. The forged, Teflon‑coated body is easy to live with, the labeled controls simplify setup, and the three included nozzle sizes cover primer through clear without extra purchases. The compromises—a so‑so regulator, the occasional accessory blemish, and a modest stock cup—are manageable and, in my experience, don’t detract from the results on the panel.

If you’re outfitting a home garage or a small shop and want a reliable LVLP that punches above its price, the D1 is an easy tool to keep within reach.
