What is the minimum order quantity (MOQ) for Marckeez HVLS fans?

Our MOQ varies by product model. For standard HVLS fans, we accept orders from 1 unit for samples. For bulk and OEM/ODM orders, contact our sales team for a tailored quotation.

What certifications do Marckeez fans hold?

Marckeez HVLS fans hold CE, CB, and ISO certifications, plus a UL 507 test report, confirming compliance with international safety standards.

Do you support OEM and ODM customization?

Yes. Marckeez fully supports OEM and ODM. We customize blade count, color, motor specs, control systems, and packaging under your brand.

What is the lead time for orders?

Standard models ship in 2–4 weeks. OEM/ODM or large custom orders take 4–8 weeks depending on volume and specifications.

How many HVLS fans do I need for my space?

A single 24FT Marckeez fan covers up to 1,700 sqm. Use our free HVLS Fan Calculator at marckeez.com/hvls-fan for an instant estimate.

Can HVLS fans replace air conditioning in a warehouse?

HVLS fans create an evaporative cooling effect that lowers perceived temperature by 3–5°C. When used alongside HVAC, they reduce air conditioning energy consumption by 20–30%.

Can Marckeez HVLS fans be used in winter?

Yes. Marckeez fans support reversible rotation. In winter, the fan runs in reverse to push warm ceiling air back to floor level, reducing heating costs without creating a cold draft.

What motor type do Marckeez HVLS fans use?

Our fans use PMSM (Permanent Magnet Synchronous Motor) technology for high efficiency, stable torque, and long life. Both the motor and controller are developed and manufactured in-house.

How is Marckeez different from Big Ass Fans or MacroAir?

Marckeez manufactures all core components in-house including motors and controllers, offering tighter quality control and more competitive factory-direct pricing. We hold CE, CB, ISO, and UL 507 certifications and fully support OEM/ODM.
