❓ FAQ
No. KA33001 is an air dryer cartridge for the compressed air brake system, mounted on the dryer housing between the compressor and the wet tank. It removes water vapour and oil aerosol. It is not an intake air filter and will not fit an engine air cleaner.
No. KA33001 is MANN TB 1394/1 x and KA33002 is MANN TB 1374 x. Both measure 136/100/111 mm with M39x1.5 thread and 165 mm height, so either will physically screw on, but the GTINs differ, KA33001 carries a coalescing filter while TB 1374 x is the standard version, and their cross references do not overlap: T280W and P951413 here versus T250W and P781466 there. Select by OE number.
MANN has flagged TB 1394/1 x as superseded, with TB 1394/16 x as the successor at 164 mm overall height — 1 mm shorter, and that difference has no effect on installation. KA33001 is supplied to the TB 1394/1 x specification and remains available from stock.
Measure across the thread crests; M39 gives about 39 mm, then gauge the pitch at 1.5 mm. Do not size on the 136 mm housing diameter alone, because dryers of that diameter exist with other thread forms.
Follow the vehicle or machine maker's interval, typically once a year. Water or oil at the wet tank drain, air escaping at the purge valve, or brake and valve icing in winter all indicate a saturated cartridge.
