A customisable 48×15 cross flow fan platform: 10–25 W, 1,800–2,800 RPM, 50–180 CFM, 15–45 Pa, under 48 dB(A), Class B/F insulation, CE/RoHS/CCC. Voltage, barrel length, lead and connector are built to your drawing — for air curtains, heaters, ventilation units and custom appliance airflow.
Key strengths
A platform, not a fixed SKU — voltage, speed, barrel length, lead and connector are set to your drawing.
10–25 W and 50–180 CFM — covers most small air-curtain, heater and ventilation duties with one tooling family.
15–45 Pa static pressure range — tune the impeller and slot together rather than accepting a single point.
Class B or Class F insulation — selected to the ambient temperature of your appliance.
CE, RoHS and CCC conformity — supports EU, UK and China channels from one supplier.
Shaded pole motor, no capacitor — connects to AC 110 V / 220–240 V, 50/60 Hz with two leads.
Specifications
Airflow is measured at free discharge and rated voltage; with a grille, filter or heat exchanger in the airflow path, expect a 15–25% reduction.

Ordering: 1,000 pieces for platform builds. New tooling for a bespoke housing or impeller length is quoted separately and typically needs a sample approval round before mass production.
Applications
Air curtains and door blowers — The 50–180 CFM range covers small domestic air curtains up to light commercial door widths.
Heater and convector platforms — Speed and insulation class are selected together so outlet temperature stays inside the appliance rating.
Ventilation and extraction units — 15–45 Pa static pressure suits short duct runs and louvre panels.
Appliance airflow, built to drawing — Where an off-the-shelf barrel does not match the enclosure, the platform is re-tooled around your dimensions.
Matching the fan to the duty: custom builds should start from the duty point, not the part number. State airflow, static pressure, supply voltage and maximum outlet temperature — the impeller length, speed and insulation class follow from those four numbers.

Private label, custom carton and retail-ready packaging
FAQ
Can you build a cross flow fan to my drawing?
Yes. The 48×15 platform is designed for OEM and ODM work: barrel length, slot geometry, voltage, speed, insulation class, lead and connector are all set to the customer drawing. Send the duty point and the enclosure outline to start.
What is the difference between OEM and ODM here?
OEM means we build your design to your drawing and specifications. ODM means you give us the performance target and envelope, and we propose the impeller, housing and motor combination, including tooling where needed.
What information do you need for a quote?
Airflow, static pressure, supply voltage and frequency, maximum ambient or outlet temperature, available envelope, connection type and annual volume — those six inputs determine the platform and the price band.
What is the minimum order for a custom build?
1,000 pieces for a platform configuration using existing tooling. A new housing or impeller needs a tooling investment and a higher first-order quantity, quoted per project.
Are samples available before mass production?
Yes. Sample units are built to the agreed specification for evaluation and sign-off before the production order is released.
