There are 3 types of tube benders: manual, hydraulic, and pneumatic tube benders. Each type has its own advantages and disadvantages. For example, manual tube benders are less expensive than hydraulic or pneumatic tube benders, but they are also slower and require more strength to operate. Hydraulic tube benders are faster than manual tube benders, but they are more expensive and require more maintenance. Pneumatic tube benders are the most expensive, but they are also the fastest and require the least amount of maintenance.
