    Can a blower be added to a hydropak setup? I'm toying around with the idea of possibly getting a blower. There is an account near my house that I could get consistent work, but it's dry bulk and I've never run a blower and most of the setups I've seen use a shaft.

    I know that blowers require a lot of torque & HP, at least to get them started. I don't know if a hydropak and hydraulic motor could provide that or not, because every pneumatic truck I've ever driven had a shaft-driven blower. But you could check with your local PTO shop, they would be able to give you a more informed opinion.

    I don't know anything about shaft driven. My blowers of old were exhaust driven and when engine is at 2400 in the old Iron set at that level to drive them provided the pyrometer stays below 1400F the bulk unloading is possible and done often.

    What I prefer in dry bulk is plant power. In the form of about a 6 foot by 3 foot wide electronic wound motor driven by oh... 440 volts and a few thousand amps at a consistency and power to fill up a bulk to 14 psi tank pressure in a few moments and feed the line consistently so you can unload about 20 to 30 minutes faster. Driving the feed of the product.

    What I do not like about truck mounted blowers is sometimes in variation of atmosphere due to frontal passage or pressure systems changing etc sometimes they find that they have to cough. Once that metallic coughing starts on the blower end, exhaust driven or shaft drive, I have to take several very specific steps as fast as I can go through them to eliminate the clogging that is pending. It is not much of a problem unless you are raising product up to 150-200 feet above into the silo. At some point the product will not continue to climb the pipe well with that kind of air.

    Yes they can be. We have about 30 of them in our fleet. Need to swing my your local blower dealer with the specs on your HYD system and see if its up to the task of running a blower.

    It is all about speed.

    Drive shaft setups need to match the needed RPM, may be 150% above the engine speed depending on the size of the blower.

    I'm sure a hydro can also be specified to the speed needed.

    Purchased a Heil vacuum with a hydraulic driven Vacuum pump. and a standard up/down wet line was able to drive it at full throttle....

    Yea, you just use a hyd-motor to run the blower, normally they run off a pto on the trans, but I have driven trucks that ran them off the Power steering (not a good idea, but it was Waste Management). Garner Denver has a setup just for hydraulic driving the blower.

    A buddy of mine went to work for Fleenor. Most of their trucks have a pto/wet kit on them. Here’s the setup they have on the pneumatics they have. Pretty much any of their trucks can hook up to one and go to work.

    After taking it over with a few guys, my current system isn't strong enough to run a blower. I'd need a bigger hydraulic pump and cooler. So that being the case, I'm keeping my hydropak for the compresser & Jack shaft and if possible the product pump. I'll move the pto to the side mount and run the blower off a shaft. My mechanic has a customer who just took a blower off a truck and he's offering it at a really good price. I just have to decide if I'm going to give up the pump to be able to run dry bulk and is the cost is worth it.

    Oh by the way most transmissions can run a PTO off either side, The last truck I drove at Valley Bulk had a Wet Kit running off the right side of the trans and a Garner Denver Rock Blower running off the left side, separate PTO switches of course, never tried to run them either (probably would not work out well). Call the local Garner Denver dealer not the local mechanic, most mechanics know little about PTO setups.

    My guy installs them all the time along with wetkits and he's done numerous hydropak installs. I've verified everything he's said with the company I buy my equipment from, they're a gardner denver dealer. I was told the blower pto should cone if the bottom never the side. 8 bolts vs 6 bolt.
