Plastic Blade or Metal Blade: how do I choose?
Plastic Blade covers a wider size range and offers a Sleeve bearing option; Metal Blade rates to a wider temperature range (−40°C to +80°C) and a higher IP44 ingress protection. Check the Technical Comparison table above for the airflow difference at shared sizes.
What sizes are available?
Frame sizes range from 60mm to 280mm across 30 published groups. Square frame sizes in this range are also known as muffin fans in some industry catalogs. See the Complete Model Table above for the full breakdown by construction, size and voltage.
What voltage options do you offer?
Both constructions are grouped into nominal 110V, 220V and 380V families; the exact nameplate voltage varies by model (for example 100/125V, 200/240V or 380/420V on some sizes). Every size has a 110V-class and a 220V-class version except the Plastic Blade 158×158×50mm, which comes in 200/240V and 380/420V only. 380V-class versions are published on Plastic Blade 120×120×38mm and every Plastic Blade size from 135mm up except Ø200×62mm, and on Metal Blade from 200mm up, in three-phase and single-phase versions. Check the model table for the exact voltage at your size.
What is the UL94 flame rating on the plastic impeller?
Plastic Blade impellers are rated UL94V-0. This applies to the Plastic Blade impeller specifically; Metal Blade impellers are welded metal and don't carry a flame rating.
What is the operating temperature range for Metal Blade models?
Metal Blade is rated −40°C to +80°C. Plastic Blade is rated −30°C to +60°C, a narrower range.
What bearing options are available?
Plastic Blade offers Sleeve or Ball, specified at order. Metal Blade ships with Ball bearing only.
Do these fans include a filter or guard?
No. This range is the bare fan. For a filtered, dust-protected assembly, see Fan Filter Units instead.
What is the MOQ for OEM orders?
Standard catalog orders have a MOQ of 10 units. OEM custom-specification and private-label orders have a MOQ of 50 units. There is no minimum for samples. See Commercial Terms above for full order terms.
What is the sample and production lead time?
Samples ship in 3 to 7 days standard, 5 to 10 days for a custom specification. Production runs 15 to 20 days standard, 18 to 25 days for a custom specification.
What certifications do these fans carry?
CE marking applies across the range, and our facility holds ISO 9001 certification at the company level. Specific certificate numbers and the certified entity are available on request.
Can you customize voltage, frame size or bearing configuration?
Voltage and bearing requirements within the published range can be reviewed case by case. Non-standard frame dimensions require a separate engineering and tooling evaluation. Send your requirement and we'll confirm what's involved.
How do I choose the right size and voltage for my application?
Start with your required airflow and static pressure, then check frame size, construction, voltage and bearing preference against the model table above, or send your requirement directly for an engineering recommendation.
