2565-V2A
The easy to install, rugged 2565 allows for higher vacuum levels and provides better internal corrosion protection and longer life. Their internal sound suppression results in lower operating noise levels, which makes them well suited for noise sensitive environments like medical, dental and laboratory applications. In addition, these compact units offer high flow, pulse free air making them ideal for applications requiring consistent air pressure and air flow.

FAQs
-
Do I need a check valve on my unit for either pressure or vacuum?
Yes, a check valve should be placed inline for either pressure or vacuum applications.
-
What can happen if I run my unit in the wrong rotation?
Vane breakage and increased potential for ingestion of foreign debris can result from running units in wrong rotation.
-
How often should the filters be serviced?
Filters should be inspected, cleaned and/or replaced every 500 hours.
-
Can units be used for pressure or vacuum?
Rotary vane units can be used for either vacuum or pressure except for separate drive lubricated models which are designed to be model specific for vacuum only or pressure only.
-
Can all separate drive units be pulley driven?
All separate drive units may be pulley-driven with the exception of the 67 series which require a 56C NEMA frame motor and must be direct coupled.
-
What is the general speed for a separate drive unit?
The max speed for a separated drive unit is 1,750 rpm.
-
Do I need to lubricate this unit?
Lubricated models require AD220 oil. Oilless model do not require lubrication.
-
Where do I get AD220 oil?
You can buy AD220 oil form your local Gast Distributor.
-
What is AD220 oil and is there a substitute?
AD220 is 10wt. SAE high detergent petroleum base oil. Any substitute should be the same. Do not use synthetic oil blends.
-
How much oil do I need to supply to the unit?
Use the fill line on the oil reservoir to gauge oil consumption.
-
How do I regulate the amount of oil dispensed?
Lubricated motor mounted units use siphon lubricators which are preset to dispense appropriate amounts of lubricant. Lubricated separate drive units use gravity feed lubricators which can be adjusted to reduce oil feed rate by adding more wicking material to base of oiler.
-
What should I do if I see a drop in performance?
Remove the end plate of the unit allowing access to the vanes. Remove the vanes from the unit. Use AH255D to flush out the inside of the unit, end plate and vanes. Blow out the inside of the pump, and wipe down the vanes and reassemble the unit. You should also replace the filters at this time.
-
Do I need to grease the bearings?
No, the bearings are shielded or sea
-
What kind of flushing solvent should I use to flush out or clean my unit?
Gast AH255D flushing solvent. You should NOT use any solvent that is petroleum based, electrical conductive or flammable.
-
Can I pump a liquid thru my unit?
No, units are designed to be used for ambient air only. You should never pump a liquid with your unit. Doing so can result in vane or rotor breakage.
-
Can I pump combustible or hazardous gas with my unit?
No, Gast rotary vane units are designed for use with ambient air only.
-
Will evacuating water vapor affect my unit?
Yes, water vapors may cause unit to rust or corrode, if ingested and allowed to sit idle for a long period of time. To help prevent your unit from rusting, follow the proper shutdown procedure defined in the operation and maintenance manual.
-
What is the proper shutdown procedure for a rotary vane unit?
Proper shutdown procedures must be followed to prevent pump damage. Failure to do so may result in premature pump failure. Units are constructed of ferrous metals or aluminum which may be subjected to rust or corrosion when pumping condensable vapors such as water. Follow the steps below to assure correct storage or shutdown of the unit between uses:
After using the unit, disconnect it from your application and allow the pump to run open for at least 3 minutes.
Block the inlet port and let the pump to pull a deep vacuum on itself for at least 5 minutes. (this lets the pump get very hot and will dry out any moisture that the pump has ingested, for lubricated models, it also helps the unit pull in extra oil to protect it)
Turn off the unit but DO NOT break the vacuum, let the unit break the vacuum level through natural leakage as the unit comes to a stop. The unit is now ready for storage.
-
I bought a new unit and want to run it on low voltage but the unit is labeled as wired for high voltage from the factory, how do I rewire it?
On the side of the motor you will find a motor manufacture information label and on this label it will show or tell you how to rewire the unit for low voltage just follow the directions listed there.
-
My unit is an older model and is now in need of some parts do you offer any repair kits?
Yes, repair kits are available for most units, check the operation and maintenance manual.
-
What comes in a repair kit?
Most kits will provide everything needed for basic repair, along with an operation and maintenance manual.
-
What tools do I need to rebuild a rotary vane unit?
In most cases all you will need is a socket or box wrench.
-
How can I get my unit serviced or repaired?
Check service area of website for list of global authorized service centers.
-
Where do I get parts for my unit?
Check sales and distribution area of website for the distribution representation for your area.
