Trundean Machinery is committed to maintaining product quality and innovation, production standardization, and strict inspection system, in order to ensure that Trundean's roots blowers, pumps and diffusers can meet all customers' needs.

Trundean Machinery Industrial Co., Ltd. has built up its own brand name - TRUNDEAN - and developed it for overseas markets. Its roots blowers have been marketed to more than 60 countries, and also earned highly praise from customers. Trundean Machinery also has branches in China and Thailand. Trundean Machinery persists in the policy of "customer first, quality first, service first" to ensure customers receive quality after-sale services. 

Besides specialized in manufacturing high quality roots blowers, Trundean is also well known for other products, including submersible roots blowers, magnetic drive pumps, vacuum pumps and diffusers.

Roots Blowers:
Roots blowers are devices that can prevent cent rotor and axis deviation from external effects by improving the strength. Trundean Machinery offers a broad range of sizes, from 1.5" to 12" in outlet diameter with the application of the pressure conveyance. Its roots blowers can be designed and manufactured according to the special requirements of the customer.

Features:
1. Pressure applied - 0-0.6 kgf/cm2 1-200HP.
2. Roots blowers types: TH, THS, THW, THL.
3. Lower noise - pressure pluses are the major noise source in blowers. Trundean roots blowers design can efficiently reduce noise by approximately 5 dB.
4. Lower energy consumption - Trundean roots blowers are designed to control backflow pressure to the rotor in order to reduce energy consumption.
5. Longer bearing life - Less vibration transmitted through the lobe results approximately 20% longer bearing life.

Submersible roots blower:
Submersible roots blower is invented to use in passage trough, foam-removing trough, blow trough and air-puffing trough, is made to prevent second social effect of pollution, noiseless and extending machine life-span, and its submersible roots blowers are also available for special order with special design.

Besides, the power of submersible roots blowers is from 2hp to 20 hp, and can be applicable to pressure conveyance. However, submersible roots blowers are applied underwater, so there will be not much noise when in use. 

Features:
1. Pressures Applied - 0-0.6 kg f/cm2 2-20HP
2. Quietness - Because of its submergibility under water, there will be not much noise from the machine when in use.
3. No need for a silencer - Because it works under water, the created noise will be very low, so there will be no need to have a silencer. Under water can mean space-saving.
4. Strong structure, be relieved - The direct connect between the motor and the blower can avoid the inconvenience of traditional belt adjustments.
5. Lower energy consumption - Trundean roots blowers are designed to control backflow pressure to the rotor in order to reduce energy consumption.
6. Longer bearing life - Less vibration transmitted through the lobe results in approximately 20% longer bearing life.

Magnetic Drive Pump:
Magnetic Drive Pump is made of anti-corrosion, thermoplastic GFR-PP or PVDF and it is easy to load and unload without any special tool to replace parts. Magnetic drive pumps can be applied to wide range field such as sea-farming, PCB assembly process, chemical works and surface treatment of metals. Trundean Machinery has over 25 years in this industry, and can provide high quality magnetic drive pumps to customer.

Feature:
1. Superior combination of materials and a leak-free, seamless design.
2. Excellent corrosion resistant materials such as carbon, ceramics, etc.
3. Designed with an emphasis on improved durability.
4. Excellent corrosion resistant.
5. Featuring enhanced reliability and safety.
6. The series can be arranged with NEMA or IEC standard motor.
7. Easy maintenance disassembly and assembly

Vacuum Blower:
Trundean Machinery offers a broad ranging from 5hp to 150hp in horsepower with the application of vacuum. Its vacuum blowers can be designed and manufactured according to the special requirements of the customer.

When developing the new series of Vacuum Blowers, Trundean Machinery emphasis on noise and vibration reduction. Trundean Vacuum Blowers rotor were adopted based on its flow characteristics which are very stable even compared to the 2 lobes type. The extent of reduction can even operate the smaller unit without installing a silencer.

Feature:
1. Lower noise - Pressure pluses are the major noise source in blowers. The Trundean roots blowers design can efficiently reduce noise by approximately 5 dB.
2. Lower energy consumption - Trundean roots blowers are designed to control backflow pressure to the rotor in order to reduce energy consumption.
3. Longer bearing life - Less vibration transmitted through the lobe results approximately 20% longer bearing life.

Diffuser:
Diffuser is a special construction that can stop the backflow of dirty water when the air diffusing action stops. The cover of the diffuser is made from neoprene rubber that can resist against acid and alkali. Trundean diffusers are designed for matching with the ready-made local 4/8" faucet and are easy to install.

Features:
1. Easy to install.
2. Tough and durable construction.
3. Prevent backflow without clogging.
