Description
Here is an import roughing vacuum system. This is comprised of a roots blower model ZJC-70F coupled to a WLW-50B reciprocating oil free vacuum pump. These were retired from a facility that went out of business during the pandemic. Both units appear functional. They are rotating smoothly and appear to be pumping fine. The WLW pump has some broken glass windows as shown. These appear to just be cosmetic windows that still are sealed and look easy to replace. Otherwise, cosmetically, everything looks good apart from some paint chips from that typical import metallized green paint. The specs we found for these units is listed above, but being import, we were unable to source a manual or further detailed curves for airflow vs pressure. Flat rate LTL freight to business addresses within the continental US is flat $450. Alternatively, buyers are welcome to arrange their own freight. Local pickup, palletizing, and wrapping is complimentary.

Shipping Costs
We do not look to make money on shipping charges. We only try to cover actual postage and shipping costs. If you feel a shipping quote is too high, please contact us as we may very well be able to do better. The eBay calculator is simply one estimate and can be off at times. On some products, we offer Free Shipping to the 48 contiguous states. For Alaska, Hawaii, US Protectorates, APO/FPO please contact us for shipping costs on these items.
Turnaround Time
About 95% of our orders ship within one business day and if you let us know there is a rush, we can almost always ship the same day. Freight items usually have a 2 day turn around time.
Next Day Shipping
We can offer next day shipping on just about all our products even if it’s not shown as an option on the shipping calculator. Please contact us for next day shipping options. We usually can get products out the same day even if paid for as late as 4:00 PM MST.
Will You Reduce the Value of an Item on the Commercial Invoice to Reduce Customs Fees
No, unfortunately, we cannot reduce an item’s value on an invoice or shipping document. We understand paying customs fees is no fun (we have to pay them often as well), but lying about customs fees is against federal law and eBay policy and the fines are severe.
Can You Ship on My Account/Local Pickup
Yes, we can ship on a customer’s UPS and FedEx account. Local pickups are also accepted weekdays from 10-5 PM and by appointment.
Packaging
We take packaging very seriously and use only the best void fill and cushioning products. We have a foam in place system, full crating department, and hundreds of in-stock box sizes. We feel the added cost of the best shipping materials is worth it to make sure your products arrive safely.
Freight/Items near/over 150 lbs/ Very Large Items
Many of our products are too large to ship through small package couriers and must be shipped truck freight. We have a loading dock and get very competitive rates with all the common freight couriers. Please contact us if an eBay freight quote seems high as we can almost always beat that rate by a considerable margin. We will need a phone number and address details to schedule a freight shipment for you. As always, buyers are welcome to arrange their own freight pickups. In most cases, items will be fully crated. Depending on the size of the item there may be a palletizing/crating fee. This fee will vary depending on the size of the item. Please contact us for pricing
Payment
Payment Time
Payment is typically requested within four business days and non-payment claims are usually started after a week. Please contact us in advance if you need special arrangements.
Payment Methods
We accept Paypal and all major credit cards. We are now accepting NET30 payment plans from major companies and universities.
Returns
Customer Satisfaction
We strive for 100% customer satisfaction and will do everything possible to maintain this. Our feedback is proof of our effort to maintain very high customer satisfaction.
Product Functionality/Guarantee Policy
Unless specifically stated in a listing, all our products are guaranteed in working shape upon arrival. Due to the technical nature of many of the products we sell, we cannot test every item, but we do guarantee them working all the same. We offer a 30 day no questions asked return policy. If an item arrives damaged or defective, we will cover the cost of return shipment.
Longer Test Times/Return Policy
We completely understand that many of our automation products take a considerable amount of time and effort to implement into a machine or fully test and can often offer a longer return time/testing period if necessary. Please contact us for more details.
Returns
We offer a 30 day no questions asked return policy. No RMA number is necessary as we get very few returns. Just let us know that you wish to return an item and we will provide the necessary return information.
In the unlikely event an item is defective/damaged in shipping/ or does not match our description, we will cover the cost of return shipment either through a Paypal payment or we can send a return label. In all other cases, we do ask that the buyer covers the cost of shipment. Refunds are processed promptly and will have no restocking/return fee unless an item sold as new is not received back in the condition it was sent. In the case a new item is not returned back in the condition sent, the buyer will be charged a 20% restocking fee.
