Inline duct fan selection

Inline Box Fan Selection Snapshot

Confirm whether a single-way inline box fan fits the duct route and service space before final model approval. Final quotation depends on duct size, installation space, airflow target, static pressure, duct length, bends, voltage, frequency and quantity.

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

Source note

HF Series coverage is 100% with high-confidence parameter rows in the PIM/source database. Do not copy values across unrelated duct fan pages.

Specification policy

Use the exact HF model row for selection

Single Way Inline Box Fan technical and selection table
Spec item	How to use it	Buyer check
Airflow	Use the exact HF variant source row	Match room volume and ventilation objective.
Static pressure	Check against duct length, bends and outlet resistance	Do not choose by airflow alone.
Noise	Use documented checks dBA value and installation context	Confirm if the fan is near occupied areas.
Voltage/frequency	Confirm before order	Match local project power supply.

Application fit

Where this inline duct fan fits

Single Way Inline Box Fan is suited for boxed inline duct ventilation with serviceable installation space 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.

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.

Appliqué à ce modèle : ventilateur en ligne à caisson unidirectionnel adapté au projet, application : ventilation de gaine en ligne sous caisson avec espace d’installation accessible pour l’entretien. Ces contrôles sont exécutés par rapport à cette spécification avant l’expédition de l’unité.

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.

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.

Pour ce modèle (ventilateur en ligne à caisson unidirectionnel adapté au projet, application : ventilation de gaine en ligne sous caisson avec espace d’installation accessible pour l’entretien), la voie OEM peut partir de cette spécification de base plutôt que d’une feuille blanche.

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.
