how does it differ from 190328?

The Field King MAX 190348 Backpack Sprayer is an upgraded version of the Field King Pro 190328 Backpack Sprayer. Here is a list of the Field King MAX 190348 upgrades: 1) 21" stainless steel wand with chemical resistant poly lining. 2) Deluxe padded harness with back pad and lumbar support, adjustable shoulder straps, waist belt and chest cinch strap. This backpack harness ensures all-day comfort while you work. 3) Fold away pump handle for easy storage. Both backpack sprayers are equipped with the internal, No Leak Pump which prevents liquids from leaking down your back. The internal pressure chamber can reach up to 150 PSI allowing a straight stream to reach 30 feet (dependent on the chemical being sprayed). Also they both have Viton seals for resistance to harsh chemicals and dual filtration to prevent clogging. If you have any questions, please feel free to contact our friendly customer service at 1-800-311-9903. Thank you for your interest in our products.

does this have a built it agitator and can wettable powders be used in it

No agitation. It’s a manual backpack.

So i have a pest control company and i was looking to add a back pack - any pco out there using this or i am open to other suggestions??

HI, This unit is ideal for use with cleaning solutions, disinfectants, stains, sealants, fertilizers, herbicides, and fungicides to help beautify your outdoor areas. I don't see anything saying that it can't be used for pest control. Thanks!

does this version also come with the 25psi regulator?

It has a pressure regulator, but I think of it more as a no drip regulator that prevents the the spray that remains in the wand from dripping if the pressure gets below 25 psi. It also ensures a clean spray pattern as most nozzles don't do a good job of dispersing the spray below that pressure.
