Asahi PF-830 industrial fan review: 78 m³/min, three ways

The Asahi PF-830 is our Best airflow pick: a published 78 m³/min, more than any other fan in our roundup, on an 18-inch head that converts to a floor or wall fan, at around ₱3,500.

How much air does it move?

Asahi publishes 78 m³/min at 1,520 rpm, and that is the highest figure in this entire roundup. For context, the 16-inch PF-631 manages 71.6 and the Asahi DC-6082 manages 54.5. The 20-inch Westinghouse, which costs almost twice as much, does not publish a figure at all.

The extra comes from blade area. An 18-inch blade sweeps noticeably more air per rotation than a 16-inch one, which is why this fan can serve a carinderia, an open garage, or a sala where people are spread across the room.

What you pay for it is 100W and noise. Asahi does not publish a decibel figure, but an 18-inch blade at 1,520 rpm sounds like the industrial fan it is. This is not a bedroom machine.

Height runs 100cm to 128cm, with 90-degree oscillation.

What does the convertible design give you?

Three fans in one box, and Asahi includes the hardware rather than selling it separately. Floor and wall mounting tubes both ship in the box.

• Stand fan. The default, on the full pole.
• Floor fan. Short tube, head low and aimed up. Right for drying a wet floor or pushing air along the ground in a workshop.
• Wall fan. Head on a wall bracket, off the floor entirely. This is the useful one in a small carinderia or a sari-sari store, where floor space is money.

The wall option needs drilling and an outlet within cord reach, so decide the spot before you buy rather than after.

Is this stand fan sulit?

Around ₱3,500 as of August 27, 2026. Check the latest price on Shopee.

On airflow per peso this is the best deal in the roundup: roughly ₱45 for every m³/min, and no other fan here delivers 78 m³/min at any price. Add the fact that you are getting three mounting options in one box, and for a workspace the case is straightforward.

Running cost is the honest counterweight. At 100W and eight hours a day it draws about 24 kWh a month, roughly ₱355 at around ₱14.78 per kWh (Meralco, August 2026). That is nearly three times what a 35W DC fan costs to run. For a commercial space where the fan runs open hours, budget for it.

Asahi backs it with 1 year on parts and 5 years on the motor, the same motor cover as the home models, which matters more on a fan expected to run under load all day.

The one caution is sample size: 60 raters at 4.8, against 3,195 for the PF-631. The score is good but thin.

Who this stand fan suits

Buy this if you need to move real air in a space rather than cool one person. It is the right choice for a garage, a workshop, a carinderia, a covered terrace, or a big open sala, and the wall-mount option makes it the obvious pick where floor space is tight. If the fan is for a bedroom, this is the wrong fan and you will not enjoy the noise.

Other stand fan options to compare

If the space is bigger still, the Westinghouse WH72715 steps up to a 20-inch blade and a metal grill at around ₱6,400, though it draws 150W and runs at 75 dBA. If you want most of this airflow in a quieter, cheaper 16-inch package, the Asahi PF-631 publishes 71.6 m³/min at around ₱2,500.
