Customer:  Hello

The vacuum tube elevator equipment I purchased from you in June 2022. So far, some devices have encountered problems. Please quote some parts of the machine as follows:

RAMHOIST: Can i know if the blower stuck and dead? as you mentioned, you used the machine for sugar bags lifting, the sugar will be easy liquefied on normal temperature, which will seal the filter cartridge and casue flow blocked, you need to replace the cartridge periodly, otherwise, the blower stage will overheat and dead.

I suggest you replace the blower stage this time, as the motor should be ok to use, and pls purchase more cartridges as spare 

是风机卡死了吗？因为客户搬运的是白糖，白糖在环境温度较高的条件下，容易液化，会附在过滤器滤芯内，如果不及时清理，就会导致风机过热

Customer: The blower is now broken and cannot be used anymore.

Could you please give me a solution.

and send me a quote for 2 sets of new fans

Thank you very much

RAMHOIST: 550usd per set

need to use new one, no solution

we will add a safety valve on it

clean filter cartridge and one-way valve periodly

Once you realized the vacuum pressure decreased, pls check in time

Customer: Thank you very much

without Item 5: 4050 - 350 = 3700 USD

without Item 1 + Item 5 = 4050 - 1050 (vaccum blower whole set) - 350 = 2650 USD

So total price above: 3700 + 2650 = 6350 USD

but i have one problem, last time you just imported item 1 vacuum blower head, but not vaccum blower whole set, then when two machines come to your side, 1 machine without vaccum blower whole set, how to use? 

Customer： Dear Mr Yang,

RAMHOIST：The blower is not complete set but just blower stage (last time you bought is just blower stage), 

the whole set should be composed of motor stage, blower stage, transmission wheels, belt, mounted frame and tension unit

Customer： Dear Mr Yang,

We can make these mechanical parts ourselves.

RAMHOIST： so what you mean is except  blower stage, you can make the motor stage,  transmission wheels, belt, mounted frame and tension unit by yourself? then in previous email, the price is correct

Customer： Dear Mr Yang,

Regarding the 2 sets of vacuum machines, can you tell me how long the delivery time is to Ho Chi Minh City, Viet Nam and what the cost is?

RAMHOIST： attached PI

ETA Ho Chi Minh City, Vietnam: 30 days after receving payment

attached revised PI

Customer： I send you a draft of the contract, you can see if there are any corrections needed. If there are no problems, please sign and stamp the scan and send it back to me.

To understand better, you can make documents such as the vacuum filter sent in advance, the product part has detailed product stamps and is recorded on the export documents.
Thank you for your support.

After receiving goods: 

Customer: Dear Mr Yang,

is above handle 2022?

Customer: Dear Mr Yang,

RAMHOIST: would you send me the photos of 2022 for check, thanks

Customer: Dear Mr Yang,

RAMHOIST: 

Customer: Dear Mr Yang,

RAMHOIST: 1000 USD/set

Customer: 

RAMHOIST: 

I realised that you changed the suction cup lips, I dont know why but i am sure that the lip is not as soft as ours, so you have to use hand to press cup when try to suck the bag

our cup lips are black (attached)

Customer: The problem that customers reflect is not there but in the steering wheel operation. It's harder to control than the old set. The old set only needs to be held with two hands and gently pressed down on the fuel bag
