How to Identify and Fix Common Vacuum Problems ?

Dual-motor vacuums use one motor to create suction and a second motor to turn the brush. Two motors make units heavier, but it also gives it more suction allowing janitors to suck up a majority of dust and dirt in one pass. In addition, machines break down less because the separate motors are protected from debris.
Central vacuum systems work by creating powerful suction using a motor located in a remote area, such as a basement or garage. This motor is much larger and more potent than traditional portable vacuums.
NuTone® PurePower™ Series Central Vacuums combine powerful suction and unmatched filtration, to remove dust and other allergens from your home. Central vacuums exhaust the vacuumed air outside of your home unlike a traditional vacuum that recirculates air back into your living area.
Vacuum mops explained
Using a 2-in-1 vacuum mop allows you to vacuum unwanted dirt, dust, and hair, whilst mopping and sanitising your floor all at once. Vacuum mops often come as a single appliance but can also come with a mop attachment to go with your cordless stick vacuum.
A two-stage motor has two fans while a three stage has three fans. In addition to the Thru-Flow and Tangential Bypass motors, there`s actually a third motor type we really haven`t addressed since it is not commonly used. This is called a Peripheral Bypass motor.
Cyclonic and filtered central vacuum systems are the two main types of central vacuums, differentiated by the method used to separate dirt and dust from the incoming airstream.
Vacuum is a space devoid of matter where the gaseous pressure inside this volume is below atmospheric pressure. A vacuum pump`s main function is to change the pressure in a contained space to create a full or partial vacuum either mechanically or chemically.
For the most part all central vacuum systems are plumbed the same. There are a few systems that require different sized piping. For example Dirt Devil and Sears use a smaller pipe. If you run into this issue we have adapters to make the new power unit compatible with pipe.
As a central vacuum manufacturer we use the 120 and 240 volt motors. The 120 and 240 motors will not be adversely affected if used with lower voltages. The 120 volt motor will be fine on 110 volts. Likewise, a 240 volt motor will be fine on 220 or 230 volts.
The power unit is typically located in a garage, basement or utility room.
Broan-NuTone™ exhaust ventilation fans allow your home to exhale, eliminating humidity, odor and airborne particulates from your bathrooms, closets, mud room, laundry, work out space and more.
The reason is simple: central vacuum systems extract the dirt, dust, and debris out of the house and into the main power unit in the garage or the basement where they are then exhausted outside. Portable vacuums recycle vacuumed allergens back into the air through the exhaust.
How they work – Dual stage pumps have a low vacuum stage and a mated high vacuum stage in one assembly. The high vacuum stage takes in process gas and transfers it to a second, low vacuum stage that compresses the gas to atmospheric pressure, improving the vacuum performance of the pump.
The level you set your vacuum depends on the height of your carpet. For bare floors, use the lowest or bare floor setting, for short and medium pile carpets use a medium setting and finally, for plush carpets use the highest setting.
With a 2-stage furnace, also known as a modulating furnace, `2-stage` refers to the furnace`s indoor blower motor. It simply means that the blower motor operates at different speeds to more accurately control the flow of heated air to your home.
A two-phase motor is a system that has two voltages 90 degrees apart, which is no longer in use nowadays. The alternator is composed of two windings placed at 90 degrees from each other. They require 2 live and one ground wire that work in two phases.
Vacuum technology is usually associated with three types of flow: viscous or continuum flow; molecular flow; and a transitional range between these two known as Knudsen flow.
The pros of a central vacuum system:
More powerful than portable vacuums with 3-5 times more suction power. Central vacuum systems are quieter as the motorized suction unit is located away from living areas. No risk of dirt and debris getting blown back out of the unit, resulting in healthier indoor air quality.
A vacuum intake passage is provided within the housing for passage of air sucked in from the exterior of the housing, and a steam generator is provided within the housing to generate steam. A steam discharge passage is provided within the housing for passage of steam discharged to the exterior of the housing.
Pascal is the official SI unit for vacuum pressure and consequently widely used in physical sciences. One pascal is the force of one Newton per square meter acting perpendicular on a surface. Pascal is named after the French mathematician, physicist and inventor Blaise Pascal.
How does a vacuum conveying system work? Vacuum conveying uses the principle of negative pressure and air velocity to transfer materials through an enclosed pipe network. These types of industrial pneumatic conveying systems can be used in many production applications in the world of industrial manufacturing.
The inlet valve is in the bottom position and the outlet valve is in the intermediate position. The trap is sealed off by the inlet valve and flow through the bypass is restricted by the position of the outlet valve. The floating check valve of the outlet valve protects the trap from back pressure.
While the Airflow measurement indicates how much air the central vacuum motor can move, the Suction measurement tells us the maximum pull the motor is capable of. This is determined by sucking a 2 inch column of water vertically to its maximum height in inches.
A universal motor is typically used as suction motor across vacuum cleaners. The universal motor is a series DC-motor that is specially designed to operate on alternating current (AC) as well as on direct current (DC). Universal motors have high starting torque, operate at high speed, and are lightweight.
