What makes the SP6300 different

Honda GX160 engine — the one contractors ask for by name

There is a reason the GX160 is the benchmark for petrol-powered spray equipment worldwide. It starts reliably, runs clean, and keeps on going through a full day on site. Low maintenance, long service life, and parts available everywhere. Contractor preferred because it earns it every single day.

Pump assembly built to last

American packings and a chrome steel piston rod deliver better sealing and resistance to abrasion. Tungsten steel inlet and outlet valves handle sustained high pressure without complaint. The WatchDog Pump Protection System automatically shuts the pump down before insufficient material supply causes damage — the kind of protection that saves you thousands in repair costs over the life of the machine.

Industry-leading clutch system

Thicker clutch plates dissipate heat faster, meaning a longer lifespan under heavy daily use. High sensitivity delivers stable pressure and precise angle compensation, so your fan pattern stays consistent across an entire wall. Strong engagement and quick response keep you in control of the machine — not the other way around.

Advanced drive system

Five-level ground gears. Japanese IKO bearings. German INA bearings. Japanese lubricating grease with excellent antioxidation and thermal stability. Every component in the drive system is chosen for longevity under real working conditions — not just to look good on a spec sheet.

Aviation-grade aluminium manifold

2.4x stronger than comparable machines. Resists clogging, handles corrosion, and keeps fluid pulses smooth so your finish stays even across large surfaces. When it does need cleaning, it disassembles by hand in seconds — no tools required.

Smart control system

Real-time operation monitoring with rapid, precise pressure adjustment for whatever coating you are running. Switching between latex and epoxy? Adjusting for heat on a summer roof job? The SP6300 responds immediately and holds steady throughout.

Run two guns at once

Large-scale projects move faster when two operators spray simultaneously. The SP6300 supports dual-gun operation at up to 0.027″ nozzle size — the right choice when you need to cover serious ground quickly and efficiently.

Stainless steel frame — built for African job sites

Harsh environments, rough handling, UV exposure, dust, and moisture. The robust stainless steel frame handles all of it without corroding or weakening. This machine is designed for sites that are hard on equipment.

What can the SP6300 spray?

The SP6300 handles a wide range of coatings used across South African construction and maintenance work:

• Latex and PVA exterior paints
• Heavy anti-corrosion coatings
• Fire protection coatings
• Waterproofing membranes and bitumen-based coatings
• Industrial epoxy floor paint
• Exterior primers, sealers, and roof coatings

Suitable for large residential complexes and sectional title repaints, commercial warehouse and factory exteriors, industrial protective coating projects, construction sites without reliable power, and outdoor infrastructure projects across South Africa.

Questions before you order? Contact us — we will help you choose the right machine for your specific jobs.

What coatings can the SP6300 spray?

The SP6300 handles a wide range of professional coatings including latex and PVA paints, primers, sealers, waterproofing membranes, bitumen-based coatings, fire protection coatings, epoxy floor paints, and heavy anti-corrosion finishes. If you are unsure whether your specific coating is compatible, contact us before ordering and we will advise.

What tip size should I use for exterior walls?

For standard exterior latex or PVA on walls, a 0.019″ to 0.025″ tip is a good starting point. For heavier coatings like waterproofing or textured finishes, move up to 0.027″ to 0.033″. The SP6300 supports a maximum tip size of 0.033″ on a single gun. Always refer to your coating manufacturer’s recommendation for tip sizing.

Can I run two spray guns at the same time?

Yes. The SP6300 supports dual-gun operation with a maximum nozzle size of 0.027″ per gun. This is ideal for large surface areas where two operators can work simultaneously to increase coverage speed. Running a second gun will reduce individual gun pressure slightly — factor this in when setting your working pressure.

Does it need electricity to run?

No. The SP6300 is powered entirely by a Honda GX160 petrol engine. You need petrol and a flat surface to park it on. This makes it ideal for new construction sites, rural locations, rooftop jobs, and any project without reliable mains power.

How easy is it to clean after use?

The SP6300 features an easy-out manifold filter that disassembles by hand in seconds — no tools needed. Flush the system with the appropriate solvent for your coating (water for latex, mineral spirits for solvent-based), run it through until clear, then store. A thorough clean after each use protects the pump packings and valves and significantly extends the life of the machine.

Are spare parts available in South Africa?

Yes. Sprayair holds spare parts locally including packings, inlet and outlet valves, manifold filters, and spray tips. You will not be waiting weeks for parts to arrive from overseas. Contact us for a current parts list or to order spares alongside your machine.

How does the WatchDog Pump Protection System work?

The WatchDog system monitors material flow through the pump. If the paint or coating supply runs low or runs out entirely, the system automatically shuts the pump down before it runs dry. Running a pump dry is one of the most common causes of packing failure in airless sprayers. This feature alone can save you a costly repair or replacement.

How do I know which SP Sprayer model is right for my jobs?

The SP6300 is the right choice for most professional contractors working on residential and commercial projects — it handles one or two guns and covers a broad range of coatings. If you regularly run very high-viscosity coatings, spray continuously on large industrial projects, or need higher flow output, contact us and we will walk you through the full SP Sprayer range to find the best match.
