Inline duct fan selection

Fresh Air Inline Fan Selection Snapshot

Confirm whether a single-way fresh-air inline fan fits the duct route before final model approval. Final quotation depends on duct diameter, route direction, airflow target, duct length, bends, outlet type, voltage, frequency and quantity.

Photo note: use the product image for shape recognition, then confirm duct diameter and the exact model row before engineering approval.

Application fit

Where this inline duct fan fits

Single Way Fresh Air Inline Fan is suited for single-route fresh-air supply or exhaust duct ventilation where the buyer needs compact inline installation and a defined duct route.

For long duct runs, multiple bends, filter resistance or strict noise targets, confirm static pressure instead of selecting by nominal airflow only.

Selection guide

Duct fan selection guide

1. Define air route

Fresh air supply, exhaust, grow-room circulation or split duct route.

2. Check resistance

Duct length, bends, filter, grille and outlet resistance affect real airflow.

3. Match HF model

Use confirmed HF variant values for airflow, pressure, power and noise.

4. Confirm for quote review

Share site details before final model confirmation.

For series-level comparison, use the official Fresh Air System Series Hub. Compare by duct route, static pressure, noise target and installation access.

Frequently asked questions

Can I choose by duct diameter only?

No. Duct diameter is only the starting point. Confirm airflow, static pressure, duct length and bends.

Why confirm static pressure?

Long ducts, filters and bends reduce actual airflow. Static pressure helps avoid under-selection.

What information is needed for quote?

Send duct diameter, route, airflow target, duct length, bends, outlet type, voltage/frequency, quantity and destination.

Quality Assurance & Warranty

Fan orders are checked at the factory before shipping, because published airflow and pressure only hold if the delivered unit matches its table row.

Applied to this model: Project fit single-way fresh-air inline fan, Application single-route fresh-air supply or exhaust duct ventilation. These checks are run against that specification before the unit ships.

Airflow and pressure checkChecks cover motor start-up, impeller balance, airflow and static pressure verification, noise review and model-to-table parameter matching.
Documented complianceCE, RoHS and related files cover the listed fan families; see the documents section below.
Warranty supportWarranty for fan orders is confirmed with the quotation for your destination market.
Service parts for fansImpellers, motor capacitors, mounting brackets and common service items.

OEM/ODM & Supply Options

For distributors and contractors working on ventilation projects, the supply side adapts to your market instead of one fixed fan build.

For this model (Project fit single-way fresh-air inline fan, Application single-route fresh-air supply or exhaust duct ventilation), the OEM route can start from that base specification rather than a blank sheet.

OEM/ODMBadging, packaging and control options for fan orders, including branded cartons and manual inserts.
Airflow and pressure variantsModel selection, motor power and voltage options are reviewed against your duct calculation.
Voltage & plug optionsVoltage and plug configuration for this product line can be reviewed during quotation.
Documentation & bulk supplyCatalogues, technical sheets, available certificates, volume pricing and distributor programs for this product line.
Order quantity & lead timeMinimum order quantity, sampling and production lead time are confirmed per model and order volume — see the B2B supply page for how sourcing enquiries are handled.
