We run each unit for 12 hours straight before it leaves, just to catch any heat issues early, and we always test at max load so you can be sure it won't cut out mid-event.
Every 680W blower gets checked twice on a flow bench—one right after assembly and another after a short break-in run, because even a small imbalance in those cast iron blades can drop airflow by 40% or more, and nobody wants that. The copper windings help with heat dissipation too, which matters if you're running it six hours at a time for a weekend rental. You'll get a CE and RoHS cert with the unit, plus a 3C mark if you need it for domestic markets. We usually hold stock on these, but confirm lead time anyway—custom colors or plugs take about 20 days or so.
For batch consistency, we pull one unit per 50 and run it against a reference curve, and if it's off by more than 5%, teh whole batch gets rechecked. Basically, we don't gamble on variances you can't spot until it's on site.
It's not ideal for continuous duty above 35°C ambient tempearture—the plastic housing can handle it, but the motor life drops. For most bouncer setups you're fine, but if it's for an outdoor desert festival, you'd want to upgrade the cooling or just run a second blower. The internal fan design actually helps keep motor temps down versus axial-style blowers, another thing that wasn't obvious form spec sheet.
The retest policy is straightforward—if it arrives and doesn't match the claimed 580m³/h or 2000PA, we'll take it back no questions asked within 30 days. That comes up maybe once every 200 units or so, but we've gotten more requests since we started doing random spot checks ourselves. We also offer one free calibration check within the first year if you send it back, but shippng's on you. Most buyers just look at the COA and move on, because the real consistency issues usually show up in batch-to-batch noise levels, not pure airflow—and we've got that dialed in within 3dB across our last 500 units.
MOQ is typically 10 units for standard orders, but we can be flexible on smaller quantities for first-time buyers. Just reach out and we'll work something out.
Yes, all three are in place and we can share copies with you directly. They cover the plastic housing, copper motor, and cast iron blades, so you're good for commercial use.
Lead time is around 25–30 days after design approval, depending on the customization level. We'll keep you posted every step.
It's built for long hauls — you can run it non-stop for 8–10 hours at full 2000PA pressure. The copper motor handles heat well, so no worries there.
Absolutely, we offer OEM/ODM on plugs and voltage specs. Just let us know your requirements and we'll adjust the motor and cable accordingly.
