Leminar Air Conditioning Industries L.L.C

Rectangular Duct System

Flotek's Rectangualr Duct system is manufactured to meet the most stringent HVAC/Industrial specifications and quality standards using Leminar's vast experience and expertise in the field and its state-of-the-art equipment.

Flotek's Rectangualr Duct system is available in Leminar's range of products for various HVAC and other industrial/commercial applications.

Energy efficiency through minimum air leakage rate and indoor air quality are the basis of Leminar's engineered products.

Ducts are manufactured on CNC machinery such as Auto fold & Shearing machines, Plasma Arc Cutting machines, and Auto Seaming machines.

The following features of the 'Flotek' Rectangular Duct System are noteworthy:

Use of hot dipped galvanised steel sheet of lock forming quality as standard duct material. Also ducts can be supplied in stainless steel and aluminium in various thickness and grades.
Duct construction as per DW144/SMACNA/ASHRAE standards provides superior strength, low leakage rate and vibration free products.
No limitation on duct size. Any size of duct can be constructed.
All straight ducts are with beading along the ducts at 300mm distance, which act as stiffners and help minimizing vibration and drumming noise of duct sheet panels.
Factory fabricated and "assembly-ready" for installation.
Perfect in finished dimensions.
Special identification stickers on duct pieces cross referred to AC units/drawings/areas for an easy installation process.
Quick and easy installation without the use of special tools.
