Application: Superalloy Forge
Location: Monroe, NC
Project Summary
4,625 sq. feet of CRV-30 & CRV-108
(20) Hooded Roof Supply Fans - 48” diameter with duct extensions
(3) 40,000cfm Make-Up Air Units
(36) LV7090 Intake Wall Louvers
Project Profile
Moffitt Corporation teamed with design engineers to design a ventilation system for the Superalloy Forging Facility ATI-Allvac. Under the objective to provide “good ventilation, higher than typical ventilation”, and with the need to provide winter make-up air with a good summer draft, Moffitt set out to design the perfect system for this facility.
To achive these objectives, Moffitt utilized a Pressure Gravity System®. Using hooded roof fans and make-up air to pressurize the building, the ventilation system is able to push the warm air upward towards the ceiling. Moffitt Continuous Relief Vents were installed on the roof, allowing heat to naturally escape the facility.
The result of this design is a building that is extremely comfortable, despite the extreme heat from the metal forge, and well ventilated. Allvac is very pleased with the results.

Client: Exal Corporation
Application: Aluminum Plant
Location: Youngstown, OH
Equipment Summary
(2) Low Profile Gravity Ventilators
45’-0” runs 10’-0” Wide
(6) Hooded Roof Supply Fans
48” Filtered fans 5 HP, 1750 RPM
(6) Duct Extensions
12’ long extension w/ 45 °angle
Project Profile
Exal Corporation, a manufacturer of aluminum cans, took advantage of Moffitt’s free ventilation design and they are now reaping the benefits.
The goal was to lower the temperature at the operating floor. By improving ventilation, the hot air could rise up and out of the building, keeping the interior cooler and provide a better work environment for their personnel.
Moffitt determined that the best way to ventilate the facility was to use a Pressure Gravity System® utilizing low profile ventilators and hooded roof fans. This allowed the facility to reduce the interior temperatures at a rapid rate. In fact, the new system decreased the interior temperature by 20°F. In turn this lead to more comfortable personnel and a satisfied plant manager.
“This ventilation system has provided a dramatic improvement to our operating conditions.” -Tom Alcaro, Plant Manager, Exal Corporation
Client: Grant Allendale
Application: Forest Products
Location: Fairfax, SC
Equipment Summary
Labyrinth Gravity Ventilator System
75 ft. run of 132” wide (177,000 CFM)
Project Profile
Grant Allendale is an Oriented Strand Board (OSB) plant that utilized the Moffitt Labyrinth to ventilate it’s facility. Moffitt performed this turn-key project, desigining, supplying, and installing the ventilation system at this South Carolina facility.
Grant Allendale chose Moffitt for their turn-key ventilation solutions after Moffitt Mechanical provided the original HVAC package when the plant was first built back in 2006.
Moffitt retrofitted Labyrinth Natural Louvered Vents to this facility. Grant Allendale saw the energy savings the Labyrinth provided over the expense of powered ventilator options, and the choice was clear.
The Labyrinth is a light-weight aluminum constructed ventilator that can be applied to newly constructed facilities or retrofitted to existing structures. Moffitt has an entire line of natural ventilation products that help saves electrical, operational and maintenance costs all while providing the facility with good environmental stewardship.

Client: Severstal
Application: Flat Roll Steel Mill
Location: Columbus, Mississippi
Equipment Summary
Over 3,000 linear feet of Continuous Relief Ventilator - Provided and installed
(16) 11 ft. x 75 ft. Labyrinths, (100) 5’ W x 10’ H
Model - LV7590 Over 4,450 sq. feet - provided and installed
(5) Wall Exhaust Fans Model PF7160 with Rainhoods
Project Profile
Moffitt has completed many projects for Severstal. From new construction to retrofit projects there is only one ventilation company for this Mississippi mill. Moffitt has the capabilities to handle projects beginning to end.
With design services from Moffitt Corporation, production from Moffitt Fan and installation provided by Moffitt Mechanical, Moffitt does it all. All projects completed for Severstal have been turn-key operations.
This plant in Columbus, MS was the first plant where Moffitt utilized Computational Fluid Dynamics (CFD) in the design process. CFD is a computer program that predicts flows and transfer of energy within a building as well as using thermal imaging to identify heat sources. This allows Moffitt to more accurately determine where the heat is and how to best ventilate the building.
“In my past 20 years of Steel Mill Construction and being around the Steel Mills I haven’t put in anything besides Moffitt Ventilators.” - Severstal’s Construction Manager, Jim Bell
Client: South Texas Electric Co-Op
Application: Power Plant
Location: Pearsall, TX
Equipment Summary:
(25) 54” Filtered Wall Supply Fans with Rainhoods, Birdscreens & Filter Box with Hinged access doors & motor operated dampers.
Interior 2-Way Diffuser
Adjustable Frequency Drives & Starters
(4) 72” x 144’ Continuous Relief Ventilator with Motor Operated Dampers
Project Profile
The Pearsall Power Plant project for South Texas Electric Co-Op combined Moffitt powered wall supply fans and CRVs to generate a highly efficient Pressure Gravity Ventilation system. The input fans help push the air through the building and out through the ventilator at the ceiling.This style of ventilation can be utilized when a building’s height makes it unsuitable for natural ventilation.
The project was designed, supplied and installed by Moffitt. Moffitt worked with engineering company, Burns & McDonnell as well as general contractor Lauger Companies to complete this job.
The Moffitt 54-inch fans were equipped with adjustable frequency drives. This provides cost and electricitical savings by reducing energy by allowing the volume of air moved to match the system demand.
