Altaros Booster questions

I have found that the closer you are to the Altators CFM and PSI recommendations the better it will run, meaning less heat and water.

I have run mine with one 1.5 hp, I believe if memory serves me, it was used on my Shoeboxes, HF compresser, it made huge amounts of water and was loud and very slow.

All the California air tool compressors (CATS) below incorporated 12 inch fans strapped above the motor and pistons. The CATS are oilessless and 110Volt.

I ran it with one 2hp/125 psi 5.5 cfm CAT, it was a little better, but still put out a lot of water and not as fast as the 3 generations of Shoeboxes I have run

I went to two of the CAT 2hp/125 psi units an that speeded up things dramatically, perhaps a little better than a Shoebox in speed I used 3 media water filters .

I then went to 3 CATS. And speed went up, water problems went down.

I turned the CATS up to 135 psi from 125 PSI and speed picked up, perhaps 90 minutes to top off a 60 minute scba from to psi, one dessicant filter need changing.

You need to be as close to the max Altaros recommends to work best and keep your drive/air supply compressor(s) from being too hot and thus producing more water. You want your compressors to run at a 30/70 % on/off run time to avoid heat, water and wear. Without my 12 inch fans, I doubt my compressors would last two years.

90 psi seems to be too low in my experience. Running the two compressors you mention would not work either, they need to be matched.

Turning them up to 135 psi made a noticeable difference, but makes them difficult to tune to the same exact pressure. You need a new safety relief valve of higher relief pressure and to tune them at the switch box for the pressure. Their is a safety issue with turning them up also.

They need to be putting out that exact pressure if your cascading them, If not the highest set pressured compressor will run all the time, so I would advise against that unless you have lots of time to fuss with the pressure .

Imagine the cascaded compressor as a team of horses, they need to be matched in strength, psi in the case of the compressors or you run in circles.

Air Pressure Booster Systems

What design standards are met?

System receiver tanks have an ASME U stamp and CRN number. Boosters are designed with a minimum 4:1 safety factor.

How do I control discharge pressure?

The booster comes with a built-in pressure regulator to adjust the maximum discharge pressure. During operation the booster will provide a discharge pressure that is typically 2-10% lower than the maximum discharge pressure. It is important to note that if the flow rate varies the discharge pressure will also vary. To maintain a constant discharge pressure, MPS recommends a tank mounted system with an additional discharge pressure regulator.

What is the difference between operational discharge pressure and the maximum discharge pressure?

The operational discharge pressure is the discharge pressure the booster produces while providing the desired flow rate. This pressure is lower than the maximum discharge pressure. As the booster approaches its maximum discharge pressure, it begins to slow down and the flowrate decreases. At the maximum discharge pressure it stops cycling because all of the forces in the booster are balanced. When a booster fills a tank, it stops automatically when it reaches the maximum discharge pressure. It restarts automatically when the pressure in the tank drops.

How do I control flowrate?

The booster automatically adjusts its cycle rate to match the desired flowrate. No additional flow controls are required.

What is the operating life of an air booster system?

Air boosters are designed for 20 million cycles. The flowrate and supply pressure must be known to determine the life in hours. For example, with a supply pressure of 80 psi Model R03S will have an operating life of hours at a flowrate of 10 scfm and hours at a flowrate of 20 scfm. They can operate 24 hours a day, seven days a week.

What drive air quality is required?

Most boosters in an indoor factory environment operate problem-free on shop air with a +40&#; F pressure dewpoint and particulate filtration of 5&#; or better.

How much air is used to drive the booster?

Drive air consumption is approximately 1/2 to 1 times the amount of pressure-boosted air depending on the pressure boost ratio. For example, if 10 scfm of high pressure air is required, the Bootstrap Compressor will need 15-20 scfm of shop air, and 5-10 scfm of that air will be vented through an exhaust silencer.

What are the determinants for selecting the right system?

These common determinants help us identify the right system to meet your needs.

The company is the world’s best psv test bench supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.

• Air quality
• Supply pressure
• Discharge pressure
• Flowrate
• Continual usage vs. intermittent usage

Consult our engineering team with these determinants to select the right system.

Is there a way to tell when maintenance is required?

Maintenance is required when:

• The booster is leaking or not building pressure
• The booster is not cycling

Why do boosters fail?

The most common causes of booster failure are:

• Particulate contamination causing a jammed control valve
• Dynamic seals are worn out

MPS offers rebuild kits and rebuild services. Please call us to get a return authorization number and then we will analyze and quote the repair upon receipt. Quotes for all repairs are at no charge.

Is there a way to reduce downtime when a booster system needs maintenance?

Many customers keep a spare booster in stock. They depressurize the booster system, remove the worn out booster, and install the new booster.

Redundant booster systems are also available. A redundant booster system has a spare booster (or boosters) incorporated into the system. Valves are provided so that one booster can be completely isolated and safely removed from the system while the second booster is operating. This eliminates any downtime due to maintenance requirements.
