For Roots RAM and RCS blowers, send us the nameplate and we will confirm the Eurus match before you order.

When a Eurus swap is not the right call. H frame blowers (Roots 32, 42, 53, 65, 76 and the matching Sutorbilt and Tuthill models) have no Eurus equivalent, and we will quote another option. Interchangeable means the same footprint and connection sizes; port and shaft positions can differ slightly between brands, so a few installs need minor piping or belt guard changes, and we check before you order. If your current blower only needs bearings and seals, a rebuild in our shop may cost less than any new blower.

Eurus blower FAQ

Will a Eurus ZZ blower bolt onto my Roots URAI base?

Yes, in most installs. ZZ blowers are built dimensionally interchangeable with the matching Roots URAI, Sutorbilt Legend and Tuthill Competitor Plus frames. Small differences in port or shaft position can mean minor piping changes, and we flag those before you order.

How do I read a Eurus ZZ model number?

The digit is the gear frame size and the letter is rotor length: M for medium, L for long. A ZZ4L is a 4 frame with a long rotor, the match for a Roots 47 URAI, Sutorbilt 4L or Tuthill 4007.

Do you have a Eurus replacement for my DuroFlow blower?

Yes. Eurus MB blowers carry the same model number as the DuroFlow they replace, so a DuroFlow 4509 becomes a Eurus MB4509. The ZG tri-lobe series covers the same applications with lower pulsation. Send us your nameplate and we will confirm the match.

Which Eurus MB replaces a DuroFlow 4509?

The Eurus MB4509. It matches the DuroFlow 4509 frame, with a 1.44 in. shaft. Send us your nameplate and we will confirm the port size before you order.

Who makes Eurus blowers?

Eurus Blower, Inc. is the North American arm of Shandong Zhangqiu Blower Co., which has built rotary lobe blowers since 1968 with its own in-house foundry and ISO 9001 quality certification.

Do you service Eurus blowers after the sale?

Yes. Our pump and blower repair shop rebuilds rotary lobe blowers of every major brand, and our 24/7 emergency line covers breakdowns from 7 branches serving 14 metro areas.
