			'''Subject:''' Aluminum Construction for Blowers



			Please note that the options that state “FAN TO BE ALUMINUM CONSTRUCTION (option #23016, #23026)” are intended to specify an ALL aluminum construction, meaning wheel , inlet cone and frame. Currently, Twin City and Comefri are the only suppliers that we have for all aluminum plenum blowers, and Comefri’s offering is only available up to 28” diameter. <u>Twin City has had several late deliveries so we want to use them only when absolutely necessary.</u> We are working with Comefri’s engineering to get their product added to the ERP, but at the moment you have to use the manual option in the ERP.

			Greenheck’s APH does have an aluminum wheel, and an aluminum inlet cone is available (standard is steel). There is an option in Pro-5 for aluminum wheel (option #23051), so if only an aluminum wheel if required, we can use Greenheck.

			When all aluminum construction is requested for weight reduction, we need to pursue other options an use the all aluminum blower as a last resort. The all aluminum construction in addition to the lead time concerns is quite expensive. Our goal should be to minimize the use of all aluminum construction blowers as much as possible. Sales will continue to request all aluminum construction for “extreme coastal” units.

			If we have preliminary design that become factory orders with the Twin City blowers, we need to try and change these blowers to Greenheck or Comefri. In many cases, we have been able to change from TCF all aluminum to Greenheck and make some adjustments to the weight to keep the same weight from the submittal.

			Please let me know if you have one of these designs, and I will work with you to see what we can do. If we do determine that TC is our only option, then we will need to release the blowers as early as we can to help with lead time.

			As a reminder, Greenheck does NOT manufacture a BELT drive VERTICAL plenum blower (Direct Drive only).

'''Subject:''' Greenheck Blowers

 

Just want to remind you that we want to use Greenheck blowers as much as possible in lieu of Twin City. We have had a number of bearing failures this year with TCF, they have had issues building fans correctly, and the customer service has not been great. That being said, we must strive to maintain a working relationship with TCF because we still rely on them for aluminum construction blowers and vertical belt driven plenum blowers. Not to mention that we are seeing cost and labor savings with the Greenheck APH belt drive assemblies.

 

As of November, 2016,

Greenheck DOES make the following:

*Arr. 3 (belt drive) horizontal plenum blowers

*Arr. 4 (direct drive) horizontal plenum blowers

*Housed Arr. 4 (direct drive) horizontal (FAN CELL) plenum blowers

*Arr. 4 (direct drive) vertical plenum blowers

 

Greenheck DOES '''NOT''' make:

*Arr. 3 (belt drive) vertical plenum blowers

*All aluminum blowers (all plenums)
