Tornado PS Spotter 98220 Intake Stack Tube 19510

The Tornado PS Spotter 98220 Intake Stack Tube 19510 is the genuine OEM vacuum stack tube inside the recovery tank of the PS Series professional spotter. Tornado’s dealer catalog lists it as “Stack Tube, Intake (Spot)” and notes that it is ordered together with parts 19490, 19491 and 19937 — the tank and its related assemblies.

Tornado’s factory cross-reference returns this stack tube for the 98220 only. It is matched to this tank’s internal geometry, so a stack from another spotter is not a substitute even where the tube diameter looks the same. Call us at 763-535-0770 with your model and serial number if you need that confirmed.

What the intake stack does

The stack tube is the column that carries the airflow from inside the recovery tank up to the vacuum motor. Its job is not just to be a pipe — it is positioned and shaped so the air leaves the tank from the right height, above the recovered water, after the water has already dropped out of the airstream.

That separation is what keeps liquid out of the vacuum motor. Water arrives up the hose mixed with air, slows down as it enters the tank, and falls; the air carries on up the stack. The stack works with the float assembly that sits around it: as the tank fills, the float rises and the flapper closes the stack, shutting off airflow before water can reach the motor. Those parts only work as a set, which is why Tornado lists this one with its neighbours.

When to replace it

Replace the stack tube if it is cracked or split — a crack low down lets the motor draw air (and eventually water) from the wrong height, which both weakens recovery and defeats the shut-off. Replace it if it is distorted or out of round, because the float and flapper will no longer seal against it, and replace it if the sealing surface at the top is damaged or has lost its gasket face.

Two symptoms point here. The first is a machine that keeps taking water into the motor housing even though the float and flapper look serviceable — often a distorted stack the flapper cannot close against. The second is weak recovery with no leak anywhere else: a split stack is an internal air leak you cannot see with the tank closed. If you are replacing a vacuum motor that failed from water ingestion, inspect the stack before fitting the new one; the motor is usually the symptom rather than the cause.

Fitting notes

Check the stack’s gaskets and the float parts while the tank is open and fit them as a set rather than reassembling around worn components. Make sure the float can rise and fall freely on the new stack and that the flapper seats squarely when lifted by hand before the machine goes back into service.

Frequently Asked Questions

What does the Intake Stack Tube 19510 do on the Tornado PS Spotter 98220?

It carries the airflow from inside the recovery tank up to the vacuum motor, drawing the air from above the recovered water so the water drops out of the airstream rather than reaching the motor.

How do I know if my Intake Stack Tube needs replacing?

Look for cracks or splits, a tube that has gone out of round, or a damaged sealing surface at the top. Water reaching the motor housing despite a serviceable float and flapper, or weak recovery with no external leak, both point at the stack.

Why does Tornado list this part with 19490, 19491 and 19937?

Because the stack only works as part of the tank assembly it sits in, together with the float and flapper that close against it. Tornado’s catalog note tells you which related parts to order alongside it so the assembly goes back together complete.
