Adjustable-height pedestal axial fans delivering fresh outdoor air at operator working level in factories, warehouses, and workshops. Repositionable without floor fixing. 305 mm to 1,830 mm diameter, IS 3588 compliant. Manufacturer & exporter from Mumbai, India.
Stand Mounted Fresh Air Supply Fan — Manufacturer & Supplier, India
Vayuvents manufactures Stand Mounted Fresh Air Supply Fans on adjustable-height pedestals for factory floor fresh air supply and worker cooling. 305 mm to 1,830 mm dia, IS 3588 compliant.
A Stand Mounted Fresh Air Supply Fan is a direct-drive axial fan mounted on an adjustable-height heavy-gauge MS pedestal stand — designed to deliver a continuous column of fresh outdoor air at operator working height across factory floors, warehouses, and industrial workshops. The pedestal raises the fan to 900 mm to 1,800 mm height so the cooled fresh airstream reaches workers directly, rather than blowing at floor level or overhead.
Vayuvents manufactures stand mounted fresh air supply fans from 305 mm to 1,830 mm diameter at our Vasai, Mumbai works — providing airflows from 1,800 m³/hr to 1,50,000 m³/hr per fan. The wide-base anti-vibration foot keeps the fan stable on uneven factory floors without floor bolting, making the stand mounted fan fully repositionable — it moves to different work areas as production layouts change, unlike base-mounted or wall-mounted fans that are permanently fixed.
Equipped with high-efficiency two-stage filtration where specified, precision die-cast aluminium alloy impellers dynamically balanced to IS 3588, and IP55 TEFC motors for the dusty and humid factory environment. The slim cylindrical MS casing conserves installation space compared to wide-body propeller fans of the same airflow rating. Metal cabinet and fan blades are anti-corrosion and anti-deformation for long service life in industrial conditions.
Available in 415V 3-phase (standard for fans above 0.5 HP) and 230V single-phase for smaller models on standard workshop sockets. Vayuvents exports to UAE, Saudi Arabia, Qatar, and Oman with full IS 3588 documentation and test certificates. Flameproof Ex-d motor variants available for use in Zone 1 and Zone 2 hazardous classified areas such as paint spray booths and solvent stores.

Frequently Asked Questions
A stand mounted fresh air supply fan is a direct-drive axial fan mounted on an adjustable-height pedestal stand. The stand raises the fan to working-level height — typically 900 mm to 1,800 mm — so the fan delivers cooled fresh air directly at the operator level rather than at floor level. The stand can be repositioned to different locations in the factory as required, unlike base-mounted or wall-mounted fans that are permanently fixed.
A stand mounted fan sits on an adjustable-height pedestal that can be moved between locations — ideal for flexible, repositionable fresh air supply where ventilation needs change with production layouts. A base-mounted axial fan is bolted permanently to the floor on a rigid MS base plate — suitable for fixed installations where the fan position is determined by the building or process layout and will not change. Stand mounted fans are preferred for flexible factory use; base-mounted fans for permanent process plant installations.
Vayuvents stand mounted fresh air supply fans come with adjustable pedestal stands, typically adjustable from 900 mm to 1,800 mm height depending on the fan diameter. Smaller fans (305 mm to 460 mm) use lighter stands adjustable up to 1,200 mm. Larger fans (612 mm to 1,220 mm) use heavier stands adjustable up to 1,800 mm. The height is fixed with a locking collar at installation to direct the airflow at the correct working level for the specific application.
Yes. The stand mounted fan positioned at a doorway or louvred opening facing inward delivers fresh outdoor air into the factory — supply mode. The same fan repositioned facing outward exhausts stale or hot air through the same opening — exhaust mode. Most single-phase 230V models can be reversed by switching the motor connection. Three-phase models reverse direction by swapping any two supply phase connections at the starter.
Vayuvents supplies stand mounted fresh air supply fans from 305 mm (12 inch) to 1,830 mm (72 inch) diameter. Smaller sizes (305 mm to 612 mm) are the most common for stand mounted service. Larger sizes (712 mm to 1,830 mm) are available on heavy-duty stands and are used for cooling large factory bays — the AX-500-14-720 (1,830 mm, 50 HP) delivers 1,50,000 m³/hr for very large building ventilation requirements.
Small stand mounted fans (0.25 HP to 0.75 HP, up to 385 mm diameter) are available in 230V single-phase for use with standard workshop power sockets. All larger models (1.0 HP and above, 460 mm and above) use 415V 3-phase 50Hz. Vayuvents specifies the correct supply for each model and can supply with a DOL starter or star-delta starter for larger motors if required.
For a 1,000 sq m factory with 5-metre ceiling height requiring 8 air changes per hour, the required fresh air supply is 40,000 m³/hr. This is typically met by 2 to 3 fans of AX-300-96-360 (915 mm, 45,000 m³/hr each) or 4 fans of AX-200-28-240 (612 mm, 15,500 m³/hr each), arranged to achieve uniform coverage across the floor area. Vayuvents provides free sizing calculations based on your factory dimensions and cooling requirement.
