A mall unit has two hard limits: no open flame, and no room for ducting above the ceiling. A downdraft teppanyaki grill table answers both. The fan and the oil fume purifier sit inside the body, so nothing hangs over the griddle.
How downdraft works on site
Oil fume is drawn in at the inlet on the griddle edge. It goes through the electrostatic purifier, which removes up to 95% of particles above 0.1 micron. The fan then pushes the cleaned air out through ducting. The purifier sits ahead of the fan, so the fan handles cleaner air and lasts longer. Three practical results follow: smoke is captured at the source, an open kitchen keeps a clear sightline, and no ceiling depth is lost.
The four questions a landlord asks
Start with power: 380V three-phase five-wire, 7.5 to 8kW per unit, with spare capacity left in the unit. Extraction comes second: where the outlet goes, how the duct runs, and whether a floor or wall opening is allowed. Purification comes third: the method, the efficiency, and the cleaning interval. Delivery comes last: unit dimensions, the access route, and permitted working hours.
The outlet position is set on site — below the chef's position left or right, at either side of the table, or straight down.
Three documents to collect before signing the lease
A floor plan showing the exhaust shaft, the spare power capacity of the unit, and the openings the landlord permits. With those three, equipment drawings and an extraction plan follow within a week. Miss one and the layout is rebuilt later, at a cost that is harder to absorb than the equipment itself.
Do not forget the hot work permit
There is no flame under the griddle, but installation includes welding and grinding the counter frame. Most buildings treat that as hot work and ask for a permit, a fire extinguisher and a watchman. This step is missed often, and the delivery stops at the loading door.
Who supplies what
Equipment data, the extraction plan and the purification specification come from the factory. Permit forms are filed by the mall or the fit-out contractor. The factory behind Cookeryaki has built commercial teppanyaki grill tables since 2004. It runs 5,000+ sqm in Huai'an, Jiangsu, and keeps a showroom in Pudong, Shanghai, where buyers can test the equipment.
