Premium, quality blower packages through innovative design and superior construction.
Accurate Air Engineering offers custom fabricated blower packages with flows to 27,000 CFM, vacuum to 28 in-Hg, and pressure to 40 PSIG.
Multiple impeller styles and profiles are available to choose from in the Gardner Denver, rotary lobe product offering:
• Straight, Two – lobe: Duroflow Series and Sutorbilt Series
• Straight, Tri – lobe: RBS Series and GD-DV Series
• Helical, Tri – lobe: Heliflow Series
• Helical screw: Cycloblower Series and Cycloblower H.E. Series
Our packaging team was founded on the principle of offering superior blower packages with better performance. A history of innovation, improvement, and quality continue to set standards for the industry. The packaging team has supplied blower packages for over 30 years on an international scope, with installations in the Middle East, Central & South Americas, Indonesia, and the United States.
Blower selection is made using computer modeling software, carefully considering bearing life, % of maximum pressure, blower speed, temperature rise across the blower, and noise level. All inlet and discharge losses are factored into package performance calculations; CFM is stated at the discharge flange. Motor nameplate HP is not exceeded, even at relief valve settings. Drives are designed for maximum life and minimum bearing load, with a service factor of 1.4 for belt driven units and 2.0 for direct driven units.
State of the art design software allows for solid modeling of the blower package assembly for improved form, fit, and function. Component models can be created, as well as parts manuals. Solid modeling and constraint software allow thorough evaluation prior to construction and testing. Each individual component is carefully selected for compatibility, in terms of flow, pressure, and temperature capabilities.
Manufacturing and Testing
Critical steps in the manufacturing process such as cutting, welding, piping, assembly, wiring, and painting are performed by fabricator-welders, mechanics, and technicians experienced in their craft with a proven track record of success in producing quality equipment. The manufacturing and testing facility is in a 16,000 square feet facility, on 1 acre with overhead cranes. Every package is fully tested at operating and relief valve pressure. A test data sheet records amperage at multiple conditions, voltage, temperatures, and blower RPMs, as well as component nameplate data. The 600 AMP test facility handles up to 350HP motors. In addition, the cell has a variable frequency drive (VFD) for up to 100HP for 50 Hz testing and power measurement.
Have your own specifications and design? Let us work with you to build a package which meets your individual needs. Many of our customers are OEM’s who incorporate our blower packages into their product offering.
We are familiar with several working arrangements. In some cases, our customers give us a concept on a napkin. In others, detailed drawings and specifications are submitted for us to follow. Either way we can serve a variety of roles in the design, fabrication, and installation process.
B series is a family of PD blower packages from 2 HP to 20 HP with pressures to 15 PSIG and vacuum to 16” Hg. The “Base Mounted” design features 3/8” steel plate formed into an elevated “Top Hat” base providing a rigid mounting platform for the blower, motor and discharge silencer.
TT series is a family of PD blower packages from 10 HP to 350 HP with pressures to 20 PSIG and vacuum to 17” Hg. The classic “Table Top” design features a heavy duty structural steel frame which provides a ridged mounting platform for the blower, motor, and drive. Silencer mounting minimizes contact points with the frame reducing mechanical transmission of the silencer shell noise resulting in a lower overall noise level.
CS series is a family of enclosed PD blower packages from 2 HP to 20 HP with pressures to 15 PSIG and vacuum to 16″ Hg. The hinged “flip top” fiberglass top locks into place to stay open making access to the motor, blower and belt drive fast and easy. The weather proof design means it can be installed outdoors, noise levels vary depending on the flow and pressure but do not exceed 85 dBA at one meter free field.
Q series is a family of enclosed PD blower packages from 15 HP to 350 HP with pressures to 15 PSI and vacuum to 16″ Hg. Powder coated 16-gauge sheet metal panels are mounted to a structural steel frame that encapsulates and protects the entire blower package. The weather proof design means it can be installed outdoors, noise levels vary depending on the flow and pressure but do not exceed 85 dBA at one meter free field.
