@ questiones:
1 What is the difference between 220V and 110V? I wil;l be running material that is about 100lb/ft3
2 How quickly will an order deliver? (model 350E)

Thank you for contacting Contractors Direct.

The main difference, aside from the obvious 220 vs 110, is that a 220V setup operates with a lower amperage versus the 110V. 110V is the standard in the USA. Please contact us or Imer USA [(301) 336-3700] for additional details.

Availability depends on the exact model you are interested in. Unfortunately, we do not have contact info for you so please call us at 1-800-709-0002 to confirm.

Can you mix drypack mortar in this? I do a mix of 25 full shovels to 1 bag of portland which mixer would I need?

Thank you for contacting Contractors Direct.

Barrel mixers are not ideal for dry-pack mortar because it sticks to the side of the barrel. The Imer Mortarman 120 is better for mixing dry-pack mortar.

Let us know if you have any other questions or concerns.

Where is the cap to release the old oil to put new one in ?

The oil in this machine will not need to be replaced at any time. For that reason, there is no designated cap to empty the oil. If there were an oil leak, the gear box can be removed from the machine and separated to add more oil. However, the leak should be sealed before this is done.

Perfect addition to my business

by -

I am a small landscape contractor and do a lot of decorative stone work (edging, patios etc) and this mixer has been outstanding. After years of rentals and hand mixing, my guys actually 'fight' over who gets to operate it. Great piece of equipment!

Perfect fit for our needs


The Imer 350 with the Subaru engine turned out to be the perfect fit our our small batch needs. Imer provided a stable platform and a quality product. We called Imer directly to ask questions and we were put through immediately to a knowledgeable staff person, they answered all our questions and gave us the confidence to purchase their product. Two week in and we are not disappointed. The contractors direct sales staff were also great. Both companies will get our business again.
