Overview
The document provides technical specifications and selection guidelines for the TSR series rotary air blowers by Tsurumi Pump. These blowers are designed for compressing air or creating a vacuum, suitable for applications such as wastewater treatment and fish farming.

Specifications
The TSR series features a V-belt driven, roots type blower with a 3-lobe rotor design to reduce noise and vibration. The blowers are available in various power ratings from 0.75kW to 75kW, with discharge pressures ranging from 10kPa to 80kPa. The construction materials include gray cast iron and chromium molybdenum steel.

Performance and Selection
The performance curves and selection charts indicate the relationships between blower models, bores, revolutions, discharge pressures, and air flow rates. The document provides formulas to convert air amounts under different conditions to standard suction conditions. It is recommended to select a blower model based on cost economy or noise reduction.

Components and Accessories
Standard components include a common base, silencer, filter, safety valve, check valve, and pressure gauge. Optional accessories include an acoustic hood, T-joint, belt cover, V-belt, pulley, and anti-vibration joints.

Structural Features
The blowers have a double-sided oil chamber design for maintaining lower temperatures during high-pressure operations. High-pressure models are available with air-cooled types for discharge bore diameters of 150mm and 200mm.

Dimensions and Weight
The document provides detailed dimensions and weights for various TSR models, excluding motor and silencer weight.

Note
The motors are selected with a minimum 5% margin, and standard conditions are defined as a temperature of 20°C, absolute pressure of 101.3kPa, and relative humidity of 65%.
