This duct is manufactured by our ingenious experts using the best quality PVC materials and high-end techniques at our well established production unit. In addition, the offered PVC Duct With Continuous Suspension Strip is examined by our team of quality controllers on various parameters before dispatching from our end. The withstand temperature of this duct shall be -20 Deg.C to +70 Deg.C. Colour: White/Yellow.
The ducting will be manufactured from  non-porous, waterproof, reinforced materials made from heavy quality polyester fabric having pvc on both sides. This ducting can be used only for blower application & will be supplied in length of 25/50/100 mtrs.+/-10% complete with continuous suspension strip  special heavy duty, extra strong 100mm wide leak proof pvc couplings, velcro / zipper joints with continuous suspension strip and hooks for hanging of  the  ducting . The width of the imported material is 3.2 mtr.

Multiple Joint increases the following :

• Resistance  towards Flow of Air.
• Leakage if the Joints comes apart.
• Distorts the Circular Shape of Ducting.

Increase in cost of operation â As resistance decreases the flow of air, more electricity has to be used to get the same amount of air.
Please note we are using 100% SPECIAL VIRGIN PVC in our material, without any fillers, hence it is light weight without sacrificing the quality or strength of the material. Fillers are generally added to increase the weight to reduce the cost of PVC & fillers reduces Adhesion Strength, which directly effects joining quality of the Ducting.
The Ducting manufactured from heavy materials will create more resistance to flow of air as Duct manufactured for light weight Duct materials will take its round shape without any efforts. The Duct strength depends on the Adhesion Strength which is very high  in our Duct Material as the fabric is of open mesh which allows total fusion of both the layers of PVC through the opening of the Fabric.

This duct is manufactured using first quality nylon / polyster fabric coated with PVC on both sides. Designed with the help of cutting-edge technology as per the set industry norms, offered PVC Semi Rigid Duct is used in various industries like Tunnel, Mines and Ship buildings. Apart from this, It is suitable for both, exhaust and blowing application.
The PVC Semirigid Ducting shall be manufactured from Non porous, Water proof, reinforced material made from Heavy Quality Polyester fabric having PVC coated on both the sides. This ducting will be provided with 6â or 4" pitch heavy spiral spring steel wire reinforcement held in position with the help of welded PVC extruded  section on the outer periphery of the ducting. The above ducting will be used for both EXHAUST & BLOWER Application. The ducting will be supplied as per your requirement upto 10m length +/- 10% complete with hooks for hanging and suitable leak proof PVC Coupling Band.  We shall supply one Coupling band with every 10m long Ducting. The withstand temperature  of this duct shall be -20 Deg. C to +70 Deg. C. Colour : Yellow/White.

The special features of "RHINO" pvc semi rigid & blower ducting are as follows:

• They are well distinguished by comparatively light in weight and high potency. Our product is fabricated by covering Virgin PVC on Polyester Fabric. This process further results in very flexible and elastic and trouble free to handle duct. By covering the fabric with virgin PVC Compound that is made up of 100% new PVC without any reused scrap or fill material, we can accomplish lighter covering and less weight.
• One of the exclusive features of our quality assured ducting is that it has rings on both the ends, which makes sure 100% Leak Proof Joints. Its another advantage is that the duct does not drag apart in case the pairing band is spoiled or becomes loose due to any outside force.
• Apart from providing PVC Coupling Bands which consists of Wire Rope & Tightening Bolt as a typical Coupling arrangement, we can also offer Metal Coupling Band.
• There are Plated Spring Steel Suspension Hooks for trouble free installation from Overhead Wire Rope.
• The complete Overhead Wire Rope Assembly with Clamps, Turn Buckle, Bracket, and more are further suggested for instant installation & free lateral movement of ducting.

Compressed pvc semi rigid ducting ratio is 1:20

• Ducting is manufactured with the help of special welding process, under strictly quality control which ensures high quality leakproof welded seams.
• Ducting normally supplied complete with suspension hooks and special leak proof couplings.
• Light weight hence easy and quick to install.
• All ductings are manufactured to the highest quality standard.
• We also manufacture Reducers, "Y" and "T" Pieces as per customer specifications.
• Repair Kits availables
