Elmo Rietschle makes one as small as a CD that weighs less than a 1/2 lb. They also make them as large as 700 lbs.
So let’s look at how they compress air – I’ll just copy verbatim from Rietschle’s literature, because they explain it very well:
The gas is taken in through the inlet (1).
As it enters the side channel (2), the rotating impeller (3) imparts velocity to the gas in the direction of rotation.
Centrifugal force in the impeller blades accelerates the gas outward and the pressure increases.
Every rotation adds kinetic energy, resulting in further increase of pressure along the side channel.
The side channel narrows at the rotor, sweeping the gas off the impeller blades and discharging it through the outlet silencer
(4) where it exits the pump.
In this case, the impeller is just a fancy fan. It spins really fast inside the housing and creates pressure or vacuum, depending on which side you hook it up to. Actually, every compressor creates both pressure and vacuum, but side-channel is one of the few technologies where you can use the same pump for both with no modification. For instance, a piston compressor creates a vacuum on its inlet, but you can’t just hook a pipe up to it and use it in your process. With a side-channel pump, you can.
This the first dynamic compressor that we have spotlighted. As we mentioned before, a dynamic compressor uses a rotating element to accelerate the air and then forces it into a smaller space. I like to think of it as a traffic jam on the interstate that happened because some lanes are blocked off, and the cars are the air molecules. The cars are jammed tighter together because of the lane blockage. More cars jammed together in a tighter area is the higher pressure.
Unlike a bad day on I-95, however, side-channel technology is very useful.

A good example is the Rietschle Velocis series. It will run 40,000 hours flat out before you need to do any maintenance. There are 8760 hours in a year, so it could run 4-1/2 years non-stop without you needing to touch it. Of course, your usual work week for a compressor like this is 40-80 hours, so that’s between 9 and 19 years before any maintenance or parts are needed.
Of course, many of you haven’t heard of these before, so there must be some drawbacks.
Those are really the only cons, and they aren’t bad points – you shouldn’t use any technology outside of the limitations it was designed for. If you need to supply a continuous flow of under 10 psi, side channel blowers are usually the way to go. However, you should have a professional to help you pick one out. Once sized correctly, side channel compressors will give you years, maybe decades, of worry-free service.
Elmo Rieschle, mtengenezaji wa CD, anaamini kwamba CD inaweza kuwa na uzito wa chini ya kilo moja. Pia, inaweza kuwa kubwa kama 700 lbs. Kwa hiyo hebu angalia jinsi wao compress hewa <unk> Mimi itabidi tu kunakili neno kwa neno kutoka Rietschle ya fasihi, kwa sababu wao kueleza ni vizuri sana: Gesi ni kuchukuliwa katika kupitia inlet (1). Wakati inapoingia kwenye channel ya upande, impeller inayozunguka hutoa kasi kwa gesi katika mwelekeo wa mzunguko. Nguvu centrifugal katika blades impeller kuharakisha gesi nje na shinikizo huongezeka. Kila mzunguko huongeza nishati ya kinetic, na kusababisha ongezeko zaidi la shinikizo kando ya kituo cha upande. Mfereji wa upande hupungua kwenye rotor, kuondoa gesi kutoka kwa blades za impeller na kuifungua kupitia silencer ya nje (4) ambapo hutoka pampu. Katika kisa hiki, impeller ni tu shabiki fancy. Inazunguka haraka sana ndani ya nyumba na huunda shinikizo au utupu, kulingana na upande gani unaounganisha. Kwa kweli, kila compressor inajenga wote shinikizo na utupu, lakini upande-channel ni moja ya teknolojia chache ambapo unaweza kutumia pampu moja kwa wote bila marekebisho. Kwa mfano, piston compressor inajenga utupu juu ya mlango wake, lakini huwezi tu hook bomba juu yake na kutumia katika mchakato wako. Kwa pampu ya upande-channel, unaweza. Hii ni compressor kwanza nguvu kwamba tumekuwa spotlighted. Kama ilivyoelezwa hapo awali, compressor nguvu hutumia kipengele rotating kuharakisha hewa na kisha nguvu katika nafasi ndogo. "Ninaweza kufikiria kama msongamano wa trafiki kwenye barabara kuu ambayo ilitokea kwa sababu baadhi ya mistari imefungwa, na magari ni molekuli za hewa. """ Magari yamekamatwa kwa ukaribu zaidi kwa sababu ya kuzuiwa kwa barabara. Magari mengi yaliyojikusanya pamoja katika eneo lenye nguvu zaidi huwa na shinikizo kubwa zaidi. Kwa sababu ya hali mbaya ya hewa, I-95 ina uwezo wa kuendesha gari kwa njia ya njia ya upande.

Kuna masaa 8760 katika mwaka, hivyo inaweza kukimbia kwa miaka 4 na nusu bila kuacha bila wewe haja ya kugusa. Kwa kawaida, wiki ya kazi ya kawaida kwa compressor kama hii ni masaa 40-80, kwa hivyo ni kati ya miaka 9 na 19 kabla ya matengenezo yoyote au sehemu zinahitajika. Bila shaka, wengi wenu hamjasikia juu ya haya kabla, kwa hiyo lazima kuwe na baadhi ya hasara. Hizi ni kweli tu cons, na wao si pointi mbaya <unk> unapaswa <unk>t kutumia teknolojia yoyote nje ya mapungufu ni iliyoundwa kwa. Ikiwa unahitaji kusambaza mtiririko wa kuendelea chini ya 10psi, blowers za njia ya upande ni njia ya kwenda. Hata hivyo, unapaswa kuwa na mtaalamu kukusaidia kuchagua moja. Mara moja ukubwa sahihi, upande channel compressors itakupa miaka, labda miongo, ya huduma ya wasiwasi-free.
