What Is the Difference Between the DeVilbiss VacuAide 7305 and 7314 Suction Machines?

Wednesday, 14 August 2019

The two flagship DeVilbiss VacuAide suction machines both have reputations for offering reliable, portable and easy to use suction, and they also draw from a very similar pool of spare parts and consumables. To make things as easy as possible, we've answered the question: What Is the Difference Between the DeVilbiss VacuAide 7305 and 7314 Suction Machines?


The DeVilbiss VacuAide 7305 Portable Suction Machine (grey, left) and the DeVilbiss VacuAide 7314 Quiet Suction Unit (blue, right)

Which Unit Is Which?

Pictured above, the grey unit on the left is the DeVilbiss VacuAide 7305 Portable Suction Machine. It is the older of the two units and has been a reliable staple of care for many years. On the right above, the blue unit is the newer DeVilbiss VacuAide 7314 Portable Suction Unit.

What Is the Same?

There are several similarities between these two suction machines. To start with, they are both highly effective and capable of achieving suction up to 550mmHg – greater than the maximum needed in most medical contexts. They are also both compact and portable, measuring around 20cm³.

Both models also use many of the same spare parts and consumables, which means you can have both machines without having to worry about managing two sets of items.

What Is Unique About the VacuAide 7305 Portable Suction Machine?

The VacuAide 7305 Portable Suction Machine is generally speaking the older and less useful model, but it does hold some unique appeal. It is slightly lighter than the 7314 model, and features a different handle, which some people may prefer. The biggest draw of using this model is the price, which is currently about 10% lower than the more advanced unit.

What Is Unique About the VacuAide 7314 Quiet Suction Unit?

The VacuAide 7314 Quiet Suction Unit is the more advanced of the two machines, and its benefits span many areas. It is much quieter than the 7305 machine, and a bespoke carry bag which allows the device to be operated without exposing it only increases its subtlety. This is the perfect machine to choose if you will need to operate it in public and would rather a degree of privacy while doing so.

Significantly, it is able to drop suction down to 50mmHg, which means it can perform oral suction on infants without the risk of rupturing their cheek. It also features a more precise pressure dial, letting you know exactly how much suction you are using at any time.

Which Unit Should I Choose?

This is entirely up to your own preference! For the majority of users we would recommend the superior control and much quieter running of the 7314 Quiet Suction Unit.

For many users who are used to using a 7305 unit, however, or for those looking to save a small amount of money and who are not bothered about sound levels, the 7305 Portable Suction Machine is proficient. The only cases in which it is vital to use the 7314 Quiet Suction Unit are when treating infants, for whom the 80mmHg minimum level of suction in the 7305 would be dangerous.

Which Spare Parts Are Available for These Suction Machines?

Both the blue 7314 unit and the grey 7305 unit draw from the same comprehensive pool of spare parts and consumables – with very few parts being for only one or the other machine. If you would like to look at replacement parts and accessories please see our DeVilbiss Suction Parts and Accessories category and if you would like to look at consumables – such as filters or tubes – please take a look at our DeVilbiss Suction Consumables category.
