Universal Blower Pac EE-PAC Blower


EE-PACs advanced high efficiency screw blower system is 100% oil free and directly coupled to an induction motor for optimized efficiency. EE-PAC has proven more efficient than traditional PD blowers and achieves turbo blower efficiency over a 5:1 turndown. This modular design begins with a base configuration without an acoustical enclosure and can easily be upgraded to include a partial or full enclosure with onboard controls as desired.


Our HYBRID is the latest technology in screw blower combined with our stylish, compact 3C-PAC platform. Three rotor options available. Tri-lobe axial rotor provides lower noise and pulsation dampening for typical pressure applications. The helical five fluted rotor with axial twisted tri-lobe rotor has internal compression for high pressure ratios. The variable helix rotors offer even higher levels of efficiency.

Direct Drive

Direct Coupled Drives are an easy way to save 5% energy by eliminating belt transmission losses. If you are already utilizing a VFD, a Direct Drive system can easily be designed for immediate energy savings. Other systems can be reviewed for options without the use of a VFD as well. With the additional benefits Direct Drive offers, it is a great way to save on money and energy.

  • Save 5% with no belt friction losses
  • Lower maintenance by never having to retighten or replace belts again
  • Increase blower bearing life up to 3 times by eliminating side torsional loading
  • High torque at low RPM for starting under load
  • Lessen blower failures


UBP has always strived for energy efficient products. We have utilized screw technology and direct drive systems for decades. In order to fit an energy efficient system into your budget, we can start with one of our standard products and add flexible design options. This allows the system to fit within your budget and increases your return on investment with an energy efficient solution.
