Questions & answers
Frequently asked
What is the return policy if the machine does not suit my needs?
30-day returns. If the machine is unused and in original packaging, return it within 30 days for a full refund.
Can I get an invoice for my business / VAT refund?
Yes. We issue a full VAT invoice for every order. EU businesses with a valid VAT ID can purchase net (reverse charge) where applicable.
What warranty is included and what does it cover?
24 months EU warranty covering the motor, pump and electronics under normal professional use. Wear parts (seals, filters, tips) are excluded.
How long does it take to clean the machine after use?
About 10–15 minutes. Run water (or solvent for oil-based paints) through the pump, then flush the hose and gun. The included cleaning routine keeps the pump in top condition.
Does the machine require 3-phase power or standard 230V?
Standard single-phase 230V / 50Hz. No special wiring or 3-phase supply is needed — plug it into any normal socket.
Can the AZ-700 spray thick plaster and not just paint?
Yes. At 227 bar the AZ-700 handles thick plaster, filler and silicone facade paints, not only emulsion. Use the 519 reversible tip for heavy materials.
