GHH-Rand is one of the wor ld ’s leading high-technology compa-nies. Since over 50 years GHH-RAND develops, designs, andmanufactures oi l- in jec ted and oi l- f ree compressed a i r solut ionsfor many di f ferent appl ica t ions. We of fer a wide product range:f rom ai rends to customized compressed a i r systems, a lways wi thhighest re l iabi l i ty in the industr y. Our work is dr iven by passionto high technology and high per formance.

For product ion of our screw a i rends we ut i l i ze newest and advan-ced technologies, which a l low us to reach minimum manufactu-r ing to lerances, h igh precis ion assembly and tes t ing under ex t re-me condi t ions. The qual i ty o f our a i rends is ver y wel l known andacknowledged wor ld wide.

Our engineers cont inuously develop our products in order to fu l-f i l l and even exceed customer ’s requirements . Highest e f f ic iencyand re l iabi l i ty in the market are resul ts o f improvement o f a i renddesign and product ion processes done over the years .Our del iver y program includes bel t dr iven, d i rec t dr iven and geardr iven a i rends. The a i rends bui l t wi th h igh precis ion are sui tedfor work under the most d i f f icul t condi t ions 24 hours per day. Many fea tures and highl ights o f the a i rends a l low to our OEM-customers easy se l l ing of the i r products to end users .Recent ly we added to our famous ser ies CE & CF newest deve-lopment the ser ies OS. Wi th the new OS ser ies we reached new,higher level o f e f f ic iency of screw compressors . Simpl ic i ty o f thedesign increases i ts re l iabi l i ty.

GHH-Rotor prof i les _ provide maximum per formance and e f f ic iency – more volume f low wi thless motor power

Bear ings arrangement _ robust radia l and axia l bear ings guarantee ex t remely long serv ice l i fe

Tr ip le l ip seal _ el iminates leakage problems through three seal ing l ips and specia l re turn path to the sect ion s ide of the a i rend

Bel t dr ive _ in any a i rend the bear ing loads created by in teract ion of medium (a i r )forces wi th ex ternal forces coming f rom bel t load.

Direc t dr ive _ rel iable solut ion for cost or iented appl ica t ions

Gear dr ive _ makes i t possible to achieve a wide range of increased output speedsby incorporated gear box

Base and face mount ing _ f lex ib le f i ts to every package design

Exchange a i rends program _ we provide our customers wi th exchange a i rends and rebui ld k i ts
