Noise Reduction for Blower Systems: Meet OSHA Requirements on any Budget

OSHA’s hearing conservation program is designed to protect workers with significant occupational noise exposures in various industry sectors from hearing impairment even if they are subject to such noise exposures over their entire working lifetimes.  All employers are required to implement a Hearing Conservation Program where workers are exposed to a time weighted average noise level of 85 dBA or higher over an 8 hour work shift.

As a market leader in blower system engineering and manufacturing, Universal Blower Pac naturally understands this impact on plant managers and how best to control noise exposure for system operators. As a result, UBP has been providing state of the art sound enclosure solutions for a variety of blower systems and industrial equipment since 1979. We manufacture both standard, semi-standard and custom enclosures to help meet OSHA requirements on any budget, whether we provided the original blower system to you or not.

The ATTENU-PAC is a full sound enclosure solution and comes in variety of sizes with various options. Choose from standard sizes, or engineers can make sizing adjustments to get exact fit.

>> Can achieve 25-30dBA sound reduction
>> Choose from hinged or removable panels with full doors on one or both faces
>> Designed with heavy 16-gauge steel combined with high density foam
>> Engineered for extreme weather conditions (heavy snow and corrosive environments). Treated with galvanneal and powder coated
>> Vent boxes remove direct line of noise
>> Door handles are designed with compression lathes to ensure tight closures and minimize noise escape
>> Extended oil drain options for easy maintenance along with 80% door coverage for easy access
>> Standard enclosures can be modified to fit on-site equipment

UBP has mastered the ability to reach acceptable noise levels with the ACOUSTI-PAC partial enclosure. This achieves up to 60% noise reduction of the ATTENU-PAC for 30% of the cost. The enclosure is designed to compactly fit around the blower, the loudest noise source. We then acoustically treat the discharge based upon frequency ranges to minimize the secondary noise sources.
>> Engineered with the same quality materials and options that the ATTENU-PAC offers, just smaller
>> Can achieve up to 15 dBA sound reduction to meet 85 dBA site requirements
>> Blower is fitted with oil and fill drain extensions for easy maintenance

Our enclosures are designed to meet whatever difficult site issues, sizing, or specialty application desired. Enclosures can be designed to be lowered over existing equipment by forklift or crane or pre-built panels to be installed on site around the equipment.

Custom enclosures can be designed for any type of equipment or blowers from multi-stage centrifugal to direct drive designs. A variety of options of materials and specialty features can be requested: larger vent box designs for increased airflow, removable doors or roofs, clam shell design for full walk around access, and much more.

UBP Engineers are available for site visits to help advise on specialty sizing or installation issues and make recommendations on how best to achieve OSHA requirements for any equipment.

Kirksville, MO WWTP Post Aeration Basin Updated with UBP Blower Systems

As mDirect Drive blower system and noise enclosureany cities around the country face new state and federal standards that demand higher regulations for their municipal facilities, the City of Kirksville, Missouri Wastewater Treatment Plant prepares to undergo new improvements to ensure compliance with the tougher standards.

The plant improvements have three major phases including headwork’s and flow control, biological treatments, and solids handling with a total cost for the project around $18 million and began in the spring of 2015.

The engineer of record is HDR Engineering. The general contractor awarded the project is River City Construction. Universal Blower Pac’s representative is Ressler & AssociatesKirksville WWTP loading blower systemUniversal Blower Pac is providing five tri-lobe blower systems to service the post aeration basins.

SOLUTION PROVIDED

Each blower provides up to 2560 SCFM at 10.5 PSIG on a VFD. The tri-lobe blowers are direct coupled with 250HP motors in ATTENU-PAC enclosures.

EXPECTED RESULTS

  • Direct drive design provides up to 5% energy savings versus v-belt driven blowers at the design point
  • Direct drive design eliminates belt maintenance and replacement
  • Up to 60% energy savings due to VFD control versus a constant speed system
  • Up to 25 dba noise reduction with the ATTENU-PAC full enclosure design

EE-PAC High Efficiency Screw Blower Walk Through and Test

In this video, Andrew Placek, Engineer and Sales Manager at Universal Blower Pac, walks through and tests the advanced features of the EE-PAC. Click here to see it!

The EE-PAC offers a low maintenance, low noise, advanced high efficiency screw blower system that delivers air efficiently across its entire operating range. This patented design is 35% more efficient than traditional PD blowers and achieves turbo blower efficiency over a 5:1 turndown, but able withstand higher pressures and temperatures to negate risk of surge or hassle with complex controls, thus ensuring reliable performance and longevity.

Turbo blowers typically only meet a 2:1 turndown before surging and have limited operating and pressure ranges as well as expensive costs due to blower failures requiring entire unit replacement. The EE-PAC features a positive displacement compressor and won’t surge, thus allowing for operation of multiple units on a single header. Unit repair is inexpensive and can be serviced from multiple sources to minimize downtime.

To receive more technical specs, drawings, or discuss how this efficient, standard positive displacement blower system can help you achieve your plant’s system needs, please email our Sales Engineering team at sales@universalblowerpac.com.
